Are you planning a road trip and need extra storage space for your luggage? Or perhaps you’re an outdoor enthusiast looking for a way to transport your gear safely? Whatever your needs, a roof cargo box can provide the solution.

In this guide, we’ll explore some of the largest rooftop cargo boxes available on the market.

What is a Roof Cargo Box?

A roof cargo box, also known as a rooftop box or cargo carrier, is a storage container that can be mounted on the roof of your car. They come in various sizes, with the biggest roof box for cars offering up to 22 cubic feet of additional storage space.

Many cars have limited cargo space, but these big roof cargo boxes provide enough room for all your belongings, even when traveling with children, pets, or camping gear.

Both hard-shelled cargo boxes and soft-sided rooftop sacks keep cargo secure from intrusive thieves while also protecting against the elements, but there are some important differences between the two styles of cargo carrier.

Key Differences Between Cargo Bags and Cargo Boxes

We have a complete comparison guide between cargo boxes and cargo bags here

A hard rooftop cargo carrier, also known as a roof cargo box, requires crossbars and a roof rack framework. Although they are more costly and difficult to install, they provide better security for high-value things such as skis, snowboards, or other open-air gear used for camping or bicycling. Your hard shell rooftop cargo box will come with a secure locking system.

On the other hand, a cargo bag uses a simple tie-down systems with adjustable straps, robust hooks, and zippered pockets and can be loaded on top of a car roof even without the use of rack systems. Many soft cargo carriers have watertight seams that are welded or taped, and also provide secure locking systems.

Soft roof packs are lighter, less demanding to stack and store, and do not require crossbars, but they’re constrained in what they can safely carry, and indeed, even though numerous of the best-rated items are made of strong and weatherproof materials, they can still break or drop separated at the creases.

Best Long But Compact Cargo Box: INNO BRM660BK Wedge Cargo Box

If you park in a garage or in enclosed parking lots frequently, you should think hard about getting a rooftop box that has a large capacity but slimline design. 

Many of these rooftop boxes add nearly two feet to the height of your car’s roof (including the height of the box and the rack), which is a no-no for SUVs and minivans.

The good news is that those who need to keep a low profile have a range of options. The INNO BRM660BK Wedge Cargo Box is one of the best-looking wedges in the category, with a contoured shape that provides 11 inches of depth while only rising 9.6 inches above your rack’s crossbars.

The Wedge has more to offer than just clearance: it features a high fit and finishes, with tool-free installation, a beautiful and aerodynamic form that reduces wind noise while accommodating a rear antenna and door, and a dual-sided opening that improves access and organization.

You’ll only get 11 cu ft of storage, which is well shy of the largest models we’ve discussed here, but bear in mind that it can still hold 6 snowboards, or 8 skis – which is still pretty impressive for something so slimline.

The INNO is the most low-profile rooftop box on the market, but a few versions come close behind. The Thule Pulse Alpine (also 11 cu. ft.) rises 11.3 inches off the crossbars (almost 1.5 inches higher than the Wedge 660) and only opens on the passenger side, but it costs under $500.

Largest Roof Bag: RoofPax Car Roof Bag and Rooftop Cargo Carrier

Although we are creeping into cargo bags territory here rather than boxes, we couldn’t leave this one off when discussing the largest possible cargo solutions.

The RoofPax soft rooftop cargo carrier is a bigger cargo carrier than others in its class and is amongst the best quality with a capacity of 19 cubic feet.

This cargo bag is tough and has dual-seam technology and waterproof double zippers. It also has a double water-repellent coating, making it a watertight load carrier. It also comes with a lifetime warranty on buckles and zippers and can be used with or without roof rails.

It has a protective pad built-in and ten elastic Velcro straps and grows to about 20 inches in height when filled to capacity. It has a 47.2-inch long and 35.4-inch-wide footprint.

This product also comes in a slightly smaller 15 cubic-foot bag which extends to the same height but has a smaller footprint (43.3 inches long and 33.5 inches wide)

Also Consider: Fivklemnz Car Roof Bag Cargo Carrier

The Fivklemnz 15-cubic-foot roof bag has an anti-slip surface and adjustable straps to hold the carrier in place without harming the car.

This device is under seven pounds in weight and expands to almost a foot in height. It measures 43 inches in length and 33 inches in width.

Largest Overall Cargo Solution: Marksign Truck Cargo Bag with Cargo Net

So, technically, this isn’t a cargo box either. However, with a capacity of 26 cubic feet, we couldn’t pass up Marksign’s colossal alternative if you really want to maximize your cargo carrying capacity.

It measures 51 x 40 x 22 inches (130 x 100 x 55cm) and has enough room to contain everything you’ll need on your trip. This fits neatly on any vehicle bed for those of you with trucks.

This product contains four heavy-duty rubber handles to make it easy to move. We looked at several designs and found this one to be a lot easier to work with.  It’s waterproof, and each bag comes with a heavy-duty 4′ x 6′ bungee net to keep the bag tight on your truck.

The net measures 8 feet by 12 feet and keeps your bag from blowing up while you’re driving. To provide a solid tie-down, Marksign contains 12 robust metal carabiners. 

The cargo bag is electrically welded from 500D tarpaulin without any microscopic holes to keep water out. Vinyl is used to coat the zipper.

The seals include velcro-closed flaps, so you can be sure to keep the rain out. Because the material is UV-resistant, it will last for a long period. 

The cargo bag comes with extra drawstring bags for storage of the cargo bag and net as a bonus.

Best Large Cargo Carrier

We must admit that we were undecided when it came to selecting our favorite rooftop cargo box. With a high-end fit and quality, very easy-to-use mounting hardware, and a slide lock handle and lock mechanism that’s hard to better, the Motion XT is undoubtedly the “best” all-rounder.

However, not every user requires the greatest, especially when “very good” can suffice for far less. And therefore, we see the Yakima Skybox on more rooftops than any other carrier: for under $600 for the 16-cubic-foot model ($649 for the 18-cubic-foot model), you get robust storage for your goods as well as a tool-free installation that works with most factory and aftermarket racks.

There’s a Skybox for everyone, with sizes ranging from 12 to 21 cubic feet and options including a low-clearance (“Lo”) model and a compact “12” that allows enough room on your rack for a bike or boat. 

Both the Motion XT and the Skybox are made to survive the rigors of the road, with tough ABS plastic and aerodynamic forms that taper at the back to fit your car’s antenna and hatch.

However, details count, and the Yakima falls short here. The turn handle requires a touch more energy than the Thule’s and isn’t as simple to operate with only one hand (it also tends to get stuck when frozen).

Biggest Roof Rack vs. Largest Capacity Roof Box

While the biggest roof rack provides a platform for carrying various items, the largest capacity roof box offers enclosed storage space, protecting your belongings from the elements. The choice between the two depends on your specific needs and preferences.

How to Choose the Biggest Roof Cargo Box

Compatibility with Roof Length

If you have a top-hinged trunk, it’s critical that the box fits smoothly with the roof and rack of your vehicle. To begin, move the front crossbar forward as far as possible (some are not adjustable). Then open the hatch and measure the back hatch to the middle of the front crossbar of the vehicle.

That distance must exceed the cargo box’s hatch clearance, as indicated on the manufacturer’s website. You’ll also want to ensure the length doesn’t obstruct visibility or interfere with any antennae in the front.

Setup of the Rack

This is rack 101 if you’ve never had a rooftop setup before. The mount is a component that mounts to the top of your vehicle and runs lengthwise (front to back). Vehicles typically have factory mounts such as raised rails, tracks, or permanent points.

If you’re working with a blank roof, you can either install a rack permanently or choose a system that works with the door jamb. 

Two crossbars or load bars are attached to the mount through four appropriate towers and are perpendicular to the roof. Crossbars come in a variety of sizes and shapes.

Each cargo box requires unique crossbars, so check to see if those crossbars are suitable for your vehicle and mount or if an adapter is needed.

Carrying Capacity & Purpose

Look at your gear before you go shopping for a rooftop cargo box. What do you need and plan to bring on your trips? Camp chairs and sleeping bags, for example, are typically shorter or packable and fit nicely in rooftop cargo bins.

For example, skis, paddles, golf clubs, and strollers will require a larger box; ensure the boxes’ inside dimensions match the length of your equipment.

To help visualize the entire volume, read the width and height of each box. The cubic-foot gear capacity is also listed on the boxes (or inches or liters). The larger your group is, the more space you’ll need for everyone’s gear.

Weight

There are two weight factors to consider: the cargo box weight and the box’s weight capacity. Without any cargo, the weight of the cargo crates shown below ranges from 20 to 66 pounds. The bulk of these carriers can comfortably carry up to 165 pounds. However, some can only carry around 110 or even 50 pounds.

If you need to move bigger objects, don’t skimp on the cargo box’s structural integrity. Stowing your heaviest items inside the vehicle, such as a fully loaded cooler, is easier and safer. Weight limits for each box should be checked with the manufacturer. Check your vehicle’s owner’s manual for the suggested maximum load as well.

Cargo boxes are made of tough plastic, and a few feature extra reinforcements, such as the steel around the bottom of the Thule Vector. 

Others have an extra layer of protection to increase their durability and weather resistance. The Pelican BX140R Cargo Case, for example, has a corrosion-resistant coating.

The quality of the hardware, such as latches and lock systems, varies, which is reflected in the price. Overall, the weight of the box is influenced by its size and materials.

Resistant to Water

Due to a waterproof exterior and weather sealing, most rooftop cargo box designs are quite weather-resistant, and they’ll generally perform a good job of blocking snow and rain.

None of these cargo crates, on the other hand, claim to be entirely watertight. Any water-sensitive or valuable cargo should be stored in a dry bag or within the rig.

Optional Extras

Extra features for comfort, practicality, and ease of use are included in a few of the top-shelf designs. For example, we like the Thule Vector’s inside LED lights and the Yakima CBX Solar’s integrated solar panel with two USB connections.

Frequently Asked Questions on Large Cargo Boxes

The post Largest Rooftop Cargo Carrier in 2026 appeared first on Family Road Trip.

Roof racks can significantly impact fuel economy, depending on the roof rack type, the speed you’re driving, and the car’s size. For example, a small roof rack on a sedan driven in the suburbs may not significantly impact fuel economy, while a large roof rack on an SUV on the open freeway may.

What Are Roof Racks?

Roof racks are a special type of device specifically designed and attached to the rooftop of a vehicle using various connecting systems to transport very bulky items such as bikes, tents, bags, and much other equipment.

With a roof rack fitted on a vehicle, some of these bulky items can be moved from the vehicle trunk or the back seat and placed on the roof, expanding your vehicle’s cargo-carrying capacity.

What Are The Different Types Of Roof Racks?

There are various types of roof racks. We will take you through the different types of roof racks in this article and provide you with a guide on how to check the roof racks that are the best fit for your car and how to install them.

Square Roof Racks

This is a simple type of roof rack, made from steel with a square bar shape. It is usually very cheap.

Aluminum Roof Racks

This is a type of roof rack made from aluminum. It is lighter in weight and has several aerodynamic properties. They should be corrosion-resistant and capable of withstanding extreme weather.

Effects Of Roof Racks On Fuel Economy

The addition of a roof rack on any vehicle can affect fuel economy.

It’s important to understand the fact that any adaptation that leads to a change in the body shape of a vehicle automatically affects the vehicle’s economy. When you put a roof rack on your car, it sticks out higher than the vehicle’s normal roof line and changes how air flows around it.

When you drive with an addition to your roof, be it just the rack or the roof rack with a basket, a cargo bag, or a cargo box attached, the car has to work harder against the wind, which uses more fuel. This extra effort against the wind is called “wind drag.”

Wind drag, or wind resistance from a roof rack can be a significant factor in the fuel economy of both sedans and SUVs.

When a roof rack is installed, especially if it’s carrying bulky items, it disrupts the vehicle’s aerodynamics. This means the vehicle has to work harder to move forward, leading to increased fuel consumption.

While SUVs are generally less aerodynamic than sedans to begin with, adding a roof rack can still negatively impact their fuel efficiency.

How Do I Know The Best Fit Of Roof Racks For My Car?

Normally, most roof racks are designed specifically for a specific type of car. This is the case with cars that have factory-fitted roof racks installed. However, for plain roof types of cars, it’s always important to check for compatibility with the car before purchasing.

Furthermore, ensure to check for the properties of the roof rack. Some of the properties to check for before purchasing and installing a roof rack include;

The Roof Racks’ Weight Limit

Roof rack manufacturers always have the specific weight limit of the rack boldly specified in the manual. Roof racks have varying weight capacities of 50kg to 100kg (100 lbs – 220 lbs). It’s important to note that car roofs, which are usually made from aluminum, also have their weight limits. 

To this effect, also check the car’s manual to help in your decision-making about the type of roof rack that best fits your car.

Understand Aerodynamics

Additionally, packing items in streamlined cargo boxes rather than letting them sit exposed can help reduce drag and improve fuel efficiency. Hard roof boxes may cost more than soft structured roof bags, but you should also consider the longer-term fuel saving.

Tips On Roof Rack Installation

Many people usually wonder if they can install these themselves. The answer is YES – but take care.

Roof rack installation is a simple DIY task that one can easily carry out with the right tools. Here is a list of tips that can guide you through the process of correct roof rack installation;

1. Ensure to Get a Helping Hand or an Assistant

This will help you carry out the job easily and quickly while reducing the chance of accidents and damages; unless you’re extra tall and strong, lifting items above your vehicle requires a fair bit of work and muscle power.

2. Carefully And Thoroughly Study the Instructional Manual 

There is a reason why manufacturers go through the process of printing instruction manuals for their products. These manuals are significant as they contain critical and essential information about your car and the impact of add-on accessories.

3. Carefully Clean Up The Car Roof

Using a soft piece of cloth, mild soap, and water, thoroughly clean the car door. This is essential, especially for cars whose roof racks must be positioned close to the door jamb. Having dirt latched in between the points of contact of the car roof and the roof rack could lead to scratches on the car paint.

4. Apply Lubricants 

The application of lubricant on the bolts of the roof racks helps to keep them away from rusting. Also, it guarantees a smooth removal of the roof racks anytime you desire.

5. Observe The Torque Settings Of Your Roof Rack. 

Ensure to study the instructions while observing the Torque settings carefully. It is always advisable not to over-tighten your roof racks as this may damage the rack or the car.

However, it is important to note that roof racks come in three distinct parts, considering the unique nature of cars in shapes and sizes.

These parts are;

• The Roof Bars

• The Foot Packs that are usually attached to the bars

• And the fitting kits. This kit is used for binding the feet to the roof.

Most cars often require three parts for attaching the roof racks to the cars. In addition, vehicles with factory-fitted rails or open rails may only require the roof racks and the foot packs for attaching the roof racks.

Other Ways to Make Your Road Trip More Fuel Efficient

Whilst we have identified that roof racks and their attached load can reduce fuel economy, it’s also worth bearing in mind these steps to improve your fuel economy when you hit the road:

• Make sure your vehicle is well-serviced and tuned before your road trip
• Check you are using the correct tires and they are inflated correctly
• Minimize the number of RPMS and keep your speed in check – higher velocity (i.e. driving faster) creates more wind drag
• Use cruise control, if your vehicle is fitted with this feature
• Do not overload your roof rack

Transporting Bikes?

Bikes on a rooftop carrier can be up to four times less fuel efficient than bikes carried on the rear of a vehicle on a hitch mount. We will cover these later in our cargo-carrying series here on Family Road Trip.

In conclusion, with an additional weight on a vehicle, there will be an effect on the fuel economy. However, due to the insignificant weight of the roof racks themselves on a vehicle, the reduction in fuel economy can be minimized by using an aerodynamic roof rack such as Thule AeroBlades.

The post Does A Roof Rack Reduce Fuel Economy? appeared first on Family Road Trip.

A car owner with a panoramic, pop-up, built-in, spoiler, removable or folding ragtops type of sunroof will no doubt be wondering whether a roof rack can be attached to their vehicle. 

This is because no car owner would want to ruin or damage their sunroof while trying to install a roof rack, as that would lead to spending extra cash to get it fixed.

Can You Attach Roof Racks On A Vehicle With A Sunroof?

Attaching a roof rack on a car with a sunroof is absolutely possible and safe as long as the process is carried out according to guidelines. To put a roof rack on a vehicle with a sunroof, you have to purchase longer bolts and clearance bars. These two tools help the roof rack to attain balance without being directly on top of the glass.

Always ensure to use the manufacturer’s manual for more directives about using a roof rack on a car with a sunroof. However, in this article, we will discuss in more detail how a roof rack can be installed on a vehicle with a sunroof.

Most importantly, do not attempt to open your sunroof with your roof rack on and carrying a load.

What Exactly Is A Roof Rack?

A roof rack is a set of bars secured to the roof of a vehicle, designed to carry bulky items such as luggage, bicycles, canoes, or skis. It provides additional storage space, especially for items that might be too large or awkward to fit inside the vehicle.

By attaching specialized mounts or carriers to the rack, users can securely fasten various types of equipment and gear, allowing for safe transportation on the road.

What Are Roof Rails?

Roof rails are the long, sturdy bars that run lengthwise on both sides of a vehicle’s roof, often raised and parallel to each other. They are the foundation for installing a roof rack system, allowing users to attach crossbars and mount various carriers.

If your car does not have rails, you will not be able to install a roof rack (though other cargo-carrying solutions are possible if you still want to use a soft roof bag with a sunroof).

Guidelines On How To Install A Roof Rack On A Vehicle With Sunroof

Step 1 Understanding The Type Of Roof Rack Your Vehicle Needs

A lot of newer vehicles come with already installed roof rails. In this case, only the crossbars will need to be attached. A car without already attached crossbars will need the entire roof rack system installed.

The primary function of a clearance bar is to protect the roof racks from hitting directly on the sunroof, thereby denting it or causing damage.

However, it is also very important to note that the type of roof rack you want for your vehicle will solely depend on the vehicle type.

Step 2 Take A Measurement Of The Sunroof Height

This measurement will help to determine how high the roof rack will be so that it doesn’t have any contact with the glass top. Also, ensure to measure to determine where to install the bolts for holding down the rack. always make good use of your vehicle manual during this process.

Step 3 Study The Installation Instructions.

Take note of the roof rack installation instructions while you open up the crossbars using the enclosed keys.

Step 4 Measure To Position The Crossbars.

Measure evenly to position the crossbars for vehicles without specification for placing the crossbars. Make sure to check for sturdiness by checking that each screw side is appropriately tightened and perpendicular to one another and must not shift when being pulled. 

Best Roof Racks For Cars With Sunroofs

There are a variety of roof racks on the market suitable for vehicles with sunroofs. Your choice of rack will depend on the type of vehicle and sunroof you have. Some of the best roof racks for vehicles with sunroofs are:

The combination of sunroof and roof racks on a vehicle adds to its weight. This is because glasses are heavy-weight objects likewise, all the components of a roof rack when joined together.

The increase in weight of a vehicle auto magically leads to an increase in fuel consumption and a reduced performance of the car.

Additional Complexity 

Sunroofs with roof racks add complexity to the car, which may also lead to certain functions going wrong. For instance, there is an increased possibility for a car with sunroofs and roof racks to leak.

Because of the uniqueness of the style of cars with sunroofs and roof racks, which makes them more desirable, there is a possibility of an increase in price for the vehicle, its maintenance cost, and accessories.

In conclusion, before considering putting a roof rack on your vehicle with a sunroof, study and understand the type of sunroof your vehicle has to determine the most suitable roof rack for your car.

Finally, always consult your vehicle’s manual for best practices and to prevent any damage whilst using a roof rack with a sunroof.

Buying Guide: How To Choose The Best Rooftop Cargo Bag For Road Trips

Since there are countless cargo bags to choose from in the market, you must know the factors to consider when shopping for one.

Here are the most important factors to remember as you shop for a rooftop cargo carrier.

Load Capacity

The carrier’s dimensions play a huge role in determining the amount of load you can carry.

If you’re shopping for a cargo carrier for a small car, you should select a compact yet adequately spacious bag with a load capacity of at least 140 pounds.

Although a medium or large rooftop cargo bag has a capacity of over 150 pounds and properly fits huge luggage, such as camping gear, ski boards, surfboards, and bikes, the carrier requires two or more individuals to fit and secure it on your car’s rooftop correctly.

Material/ Waterproof Protection

A great feature to consider when buying a rooftop cargo carrier is sturdy material and waterproofness. You certainly don’t want to invest in a rooftop cargo carrier only to break down after one or two road trips. 

Similarly, it’s not wise to invest in a bag that gets wet as you drive in the rain to a campsite. Remember, not all rooftop cargo bags are 100% waterproof. 

So, if you live in areas with heavy rainfall, it would be beneficial to buy a waterproof carrier for optimal safety for your items.

Thus, a cargo carrier with waterproof fabrics, sturdy material, and zippers are very important.

Durability

Most rooftop cargo carriers for travel are waterproof and foldable because they’re designed with a fabric material. Additionally, the bags are fairly priced but tend to wear out fast.

While the boxes are designed from rigid plastic material, the baskets are made from sturdy galvanized iron.

As opposed to bags, baskets and boxes tend to be sturdy, thanks to their durable construction. With this, the carrier will surely last you for a prolonged period.

Easy to Install

A rooftop cargo bag is reasonably light to let you mount it alone.

So, if you are purchasing a rooftop cargo bag, you must choose the one you can easily install in vehicles that don’t have racks, such as sedans, SUVs, hatchbacks, and other compact cars.

Ease of Use

A lot of cargo bags can easily fit on most car roof racks. Nevertheless, a couple of bags are made to fit cars that do not come with roof racks. Bags come with ease of installation, use, and storage. 

Therefore, if your vehicle lacks a roof rack, you need to install one to give you the ability to use a roof basket or box.

Luckily, modern roof boxes come with a dual-sided opening system that allows you to open the luggage from either the left or right side.

Besides, your luggage will be safe throughout the trip, thanks to the incorporated security system.

However, since some of them aren’t 100% waterproof, you’ll need to be extra cautious when storing electronics and other gadgets on the rooftop.

Also, it’s worth noting that baskets and boxes don’t come with waterproof and security features.

Size & Weight

Your car’s load capacity defines the size and weight of the rooftop cargo carrier. Well, you can get this info from the vehicle manual. 

After checking on your vehicle’s load capacity, shop for top-quality cargo bags with high weight limits so you can store huge luggage without worrying about overloading the car.

If you are one of those who love carrying strangely shaped luggage, you need to buy a solid carrier, such as a soft bag or a basket. 

In addition, baskets are excellent choices if you want to carry heavy and large objects because you can fasten them using straps and cords.

Design and Aerodynamics

Cargo bags need to feature intuitive and ergonomic designs that allow you to store the luggage safely, besides giving you extra space in your car.

Also, you need to consider an aerodynamic design if you want to lower your gas mileage and save money on the journey.

Unlike bags, baskets and boxes feature universal designs that embrace amazing aerodynamic performance. 

A substantial number of aerodynamic carriers are intuitive, thanks to the included mounting hardware that streamlines the installation process.

You can easily carry camping gear and sporting equipment with mounting tools.

Extra Features

As said earlier, if your vehicle has a rack, you’ll have an easy time mounting a roof box. While a roof box has a sleek design, it may limit you from carrying peculiarly shaped luggage. 

On the other hand, baskets boast a metal construction that makes them more massive than boxes.

So, a basket needs more than one person to fit it in your vehicle due to its heavy weight. Therefore, if you have a large garage, it would be beneficial to permanently install them on the car rooftop.

Conclusion

For your belongings’ safety and security, the above are the best rooftop cargo carriers you need to consider buying. 

They’re waterproof and quality bags constructed from sturdy materials, ensuring they last for a prolonged period. Besides, the bags have anti-slip tops; use them with or without rooftops.

Additionally, they are armed with buckles and straps that make them easy to attach to the side of your vehicle.  This means the bag will stay in position even when moving at high speeds.

Cargo boxes are a great way to provide more cargo space in your car, and it’s relatively cheap and easy to install. However, installing at the wrong position on your vehicle will impact a car’s aerodynamic performance and eventually lead to higher fuel consumption.

So, what is the best position for a roof box on a car? For the best stability with the least amount of wind resistance and drag, ideally, the cargo box should be mounted centrally and towards the rear of your car.

In this article, we provide advice on how to position your cargo box correctly on a car and the impact of the cargo box positioning.

Let’s get into it!

Where Should A Roof Box Be Positioned On A Car?

Ideally, the best position to install your roof box is at the center of the crossbars and slightly adjusted towards the rear of your car. 

With your cargo box positioned at the central area of the crossbars, it will add stability to the car when your cargo box is fully loaded. 

If you have a dual-side opening cargo box like Thule cargo boxes, positioning it at the center will make it easier to load and unload from either side.

In addition, it would be best to position the cargo box slightly backward, closer to the vehicle’s back.

Mounting the cargo box at this position will improve aerodynamics and inspire airflow around the box. Also, it has the least wind resistance and drags for fuel usage.

Many cargo boxes have aerodynamic and sleek designs that help reduce those issues but positioning the cargo box in the correct position will significantly help better gas mileage. 

Can The Roof Box Be Positioned To One Side?

Absolutely! You can position your cargo box to one side, especially when you have a passenger-side opening cargo box like Thule Pulse Rooftop Cargo Box.

Mounting your cargo box to the passenger side will make your family members or friends quickly access essential items from the cargo box during the brief stop on the road trip.

Positioning the cargo box to one side can benefit someone with a narrow cargo box like MeeFar Roof Rack Carrier or similar models. Because of its narrow width, you still have space on the rooftop for carrying bikes or kayaks.

MeeFar Roof Rack Carrier

However, mounting the cargo box on one side can potentially have some issues (read below).

Some Impacts You Need To Know When Positioning The Cargo Box

Having a cargo box installed on your car’s rooftop will impact and concern many cargo box owners, particularly the wind noise and gas mileage.

Also, the vehicle design contributes to the overall aerodynamic performance of a car. A hatchback car (like Subaru Outback or Honda CR-V) will perform differently than Honda Odyssey or Audi Q5.

Positioning the cargo box at different positions on the rooftop can have some impacts as follow:

• Centrally: The most ideal and recommended location where the roof box should be placed for better performance. Moreover, it is best for even weight distribution when fully loaded. It might not be ideal for those who have a passenger-side opening cargo box.

• One side (usually the passenger side): It’s ideal for the passenger-side opening cargo box for easy loading and unloading. It allows some spaces on another side for additional gears like bikes. But, weight distribution is poor, which can impact overall safety.

• Far Forward: How far forward should a roof box be? Mounting the cargo box too much forward or overhang can impact the stability of your car. It also reduces the aerodynamic effects because it increases the airflow resistance from the front windshield.

• Far Backward: One of the problems when positioning the cargo box far towards your rear is that it can interfere with the rear hatch when it is fully opened. It is true for hatchback cars. Moreover, it also causes interference with a rear antenna.

Once you have the right position for your rooftop cargo box, make sure you read our top tips for correctly packing your cargo box, and why you might not want to drive with an empty cargo box

What’s The Best Position For A Roof Box On A Car?

We’ve shown you the best position for a roof box on your car. For the best stability with the least amount of wind resistance and drag, a roof box should be mounted centrally and towards the rear of your vehicle. 

Of course, it’s entirely up to you to decide how and where you want to install it that suits your needs better. If you are unsure about doing it yourself, always ask someone or the dealer that you’ve bought the cargo box for help.

Are you looking for the best roof racks for cars without rails to carry your kayak or skis? You’re in luck! There are several different roof rack options available that will work with your vehicle, even if roof rails aren’t fitted.

When it comes to roof racks, there are a few things to keep in mind. First, you’ll want to ensure that the rack is compatible with your car.

Secondly, you’ll need to decide what type of rack best suits your needs. And finally, you’ll want to consider how easy the rack is to install and remove.

Before we go further into the details, you might want to check out our post about tips and advice for using a car-top carrier without a roof rack here.

With those factors in mind, let’s look at some of the best roof racks for cars without rails.

Related: Why Are Roof Racks So Expensive?

As Amazon Associates, we earn a commission from qualifying purchases made on this page.

Inflatable Roof Racks

If your car doesn’t have roof rails, you don’t have to miss out on the fun of taking your bike or kayak with you on road trips. An inflatable roof rack is a great solution. They’re much cheaper than a hard rack and usually range from around $50 to $150.

And they can be quickly deflated and stored away when not in use. Plus, they are very lightweight and can be easily switched between different cars.

But for lighter items like bikes, skis, snowboards, and kayaks, an inflatable roof rack is very capable of hauling those items off your car rooftop.

The installation is also straightforward and can be done in minutes.

However, there are also some disadvantages to using an inflatable roof rack. They are not as sturdy as a hard roof rack and can’t carry very heavy items like a cargo box.

So, if you’re planning on carrying a cargo box or anything else very heavy, you’ll probably want to go with a hard rack.

Plus, they must be inflated before each use which can be slightly time-consuming.

Our suggestion for the best inflatable roof rack is the HandiRack Universal Inflatable Soft Roof Rack Bars.

We recommend the HandiRack Universal Inflatable Soft Roof Rack Bars as the best soft roof rack for those who own a car without rails. The installation process is easy and can be done without any tools.

You must pass the straps through your car and attach them with a buckle. The best part is that you don’t have to inflate the bars yourself – a HandiPump is provided for your convenience.

This roof rack is durable and can hold up to 175 pounds. They’re also cushioned to protect your car’s roof from scratches. However, they may not be suitable for extreme temperatures.

In addition to that, you can’t use this rack to attach soft cargo. Overall, the HandiRack is an excellent option for those looking for an easy-to-use and durable roof rack.

Soft Roof Rack Pads

Soft roof rack pads are an excellent option for vehicles without rails and offer several benefits. One of the most significant advantages of soft roof rack pads is that they are very easy to install.

Place the foam blocks on your car’s roof and secure them with the straps. The foam block design also provides a more secure grip than other roof racks, making your belongings less likely to slip or fall off.

Soft roof racks are ideally suited for carrying your kayak, canoe, or surfboard. They are also a good choice for carrying bikes, as they will not damage the paintwork on your car.

In addition, soft roof rack pads are often more comfortable to use as they distribute the weight more evenly across the car’s surface. As a result, they are ideal for long journeys where you need to be able to access your luggage easily.

They are affordable and have a similar price range as the inflatable roof racks.

The main disadvantage of soft roof rack pads is that they can be less stable than other types of roof racks. The foam blocks can compress over time, reducing the rack’s grip and stability.

Our pick for the best soft roof rack pad is Universal Soft Roof Rack Pads from HEYTRIP.

If you’re looking for a simple, no-fuss way to transport items on your roof without rails, HEYTRIP Universal Soft Roof Rack Pads are an excellent option.

These soft roof rack pads are top-grade EVA foam to provide a soft landing for your loads and effectively reduce vibration during transportation.

It also has a built-in non-slip mat to protect your car roof surface from getting scratched and is fixed tightly to reduce wind noise. The maximum weight load of the HEYTRIP Universal Soft Roof Rack Pads is 176 lbs (80kg).

Thanks to its foldable design, it is easy to clean and store in the bag (included) when not used.

One thing to note is that the HEYTRIP Universal Soft Roof Rack Pads are installed through the door, which is likely to cause rainwater to infiltrate into the car through the straps if used in rainy weather.

So, this may not be the best option for you if you live in a rainy climate.

Overall, we think the HEYTRIP Universal Soft Roof Rack Pads are the best alternative to the inflatable roof rack for those looking for an easy-to-use, no-fuss roof rack solution for their car without rails.

Be sure to use it on sunny days to avoid water infiltration issues.

Universal Strap Attach Roof Bars

Universal Strap Attach Roof Bars are great for someone who needs to attach a cargo box or other heavy item to their car. This roof rack system comes with two load bars, towers with suction cups, and attachment straps, so you can easily install them on your vehicle.

These bars attach directly to your car’s roof using a series of easily adjustable straps. The suction cups ensure that the load bars are firmly attached to the top of your vehicle. 

The process only takes a few minutes and doesn’t require any tools, which is excellent for those who aren’t exactly handy. But you must be careful when threading the strap through the ratchet.

If you don’t thread it in the right direction, the ratchet action will pull the thread in the wrong way, making it hard to get it back out.

Once they’re in place, you can add any number of rooftop accessories, from cargo boxes and baskets to ski and bike racks, so if you’re looking for an easy-to-use roof rack solution for your car without roof rails.

The Universal Strap Attach Roof Bars system is relatively inexpensive, with the average prices ranging from $60 to $200 – depending on the length of the load bars.

The potential downside of these roof rack systems is that the suction cups can sometimes come loose. Another thing to remember is that you need to ensure that the straps are tight enough so your load doesn’t move around while driving.

But as long as you keep an eye on those two things, the Universal Strap Attach Roof Bars system is a great way to add a roof rack to your car without roof rails.

Our suggestion for a universal strap that attaches roof bars is the SEAH HARDWARE Universal Roof Rack Cross-Bars.

Buy it on Amazon

SEAH HARDWARE Universal Roof Rack Cross-Bars

The Universal Roof Rack Crossbars by SEAH HARDWARE offer a great way to transport cargo on your car without roof rails, and they come with a pair of crossbars that are 48 inches long.

The heavy-duty steel tubes make them strong and safe, and the waterproof ratchet tie-downs ensure that they will remain firmly in place on your car top.

The crossbars were not that difficult to assemble, but you must be careful when threading the strap through the ratchet and not too overtight.

The 1800 lbs ratchet tie-down ensures the roof bar will remain to sit tight on your car top. However, there are two drawbacks to this roof rack.

Firstly, it doesn’t work with a two-door car because the distance from the car roof to the bottom of the bar is 6.5 cm. Secondly, the load bar size comes with one option, which is 48 inches long.

If you’re looking for another universal roof rack crossbars option with longer load bars, I recommend you check out Malone VersaRail Universal Cross Bars.

The Malone VersaRail Universal Cross Bars have two load bar options – 50 and 58 inches. Unlike the SEAH HARDWARE Universal Roof Rack Cross-Bars, the Malone crossbars have abrasion-resistant dual suction towers for excellent stability.

Alternatives To Roof Rack System Without Roof Rails

A few options to the roof rack systems we mentioned above don’t need roof rails and aren’t too pricey.

SportRack Complete Roof Rack System is an excellent choice for those who don’t have the rails on their car. It’s easy to install and is very secure, thanks to the integrated locking system.

The rack is compatible with many accessories, so it can be used to carry a variety of items. It’s also made from durable aluminum to hold up to 130 lbs. of weight.

The downside is that the installation process can take a bit longer due to some learning curves. However, this rack provides great versatility and security for your belongings once installed.

SportRack Complete Roof Rack System

Another solution is to install a tower designed for cars without roof rails. We recommend Yakima BaseLine Adjustable Towers as the best product for this because of its excellent build quality and durability.

If you’re looking for a roof rack that’s both adjustable and versatile, the Yakima BaseLine Adjustable Towers is a great option. It can be used with JetStream, CoreBar, and RoundBar crossbars, giving you plenty of options for transporting gear.

And it locks securely to your vehicle with the SKS system. Plus, it has a maximum load rating of 165lbs. The drawback of this option is that it can be a bit expensive as it doesn’t come with load bars.

It would be best to buy separate load bars to make it a complete system. In our opinion, it is worth the investment as it’s a high-quality roof rack. It comes with a lifetime warranty from Yakima.

FAQs on Roof Racks Without Rails

Here are some frequently asked questions about the roof rack system.

Final Thoughts

If you’re looking for a way to transport large items or gear in your car without using the roof rails, there are several options available that we have recommended in this post.

We suggest using either a tower-based roof rack system for long-term usage or the soft roof racks if you carry things occasionally. Both have pros and cons, so choose the most suitable for your needs.

Safe road trip!

Are you getting ready for your next family road trip? Like most people, you’ll probably be packing your car with all sorts of things – clothes, food, camping gear, and more. But what about your luggage? 

If you’re traveling with a lot of stuff, it can be challenging to fit it all into your car. One solution is to use a roof box. 

A roof box can give you extra storage space for your belongings, and it’s a great way to keep them safe and secure while on the road. This article will share tips on how to pack a roof box for your next road trip!

12 Tips on How to Pack a Roof Box

When packing for a road trip, it’s important to ensure everything is secure. One way to do that is by using a roof box. Here are some tips on how to pack a roof box:

1. Know Your Roof Box Weight Limits

Make sure you know the weight limit of your roof box before loading it up because every roof box has a maximum weight they’re safe for. Typically, this weight ranges from 50kg to 75kg, depending on the size of your box. 

Most companies that manufacture these items place this information in plain view. If you’re having trouble determining the weight limit for your roof box, look inside an owner’s manual.

It’s important to adhere to these weight limits, as overloading a roof box can cause it to become unstable. This could lead to the box becoming detached from your car while driving, potentially causing an accident. 

Not only is this dangerous, but it can also damage your vehicle and the roof box itself.

2. Pack The Heaviest Things In The Car First

It might seem common sense, but it’s still a good idea to pack the heaviest items in the car first, even if you use a roof box. This is because the car has a greater weight limit than the roof box. 

So packing the heaviest items in the car will ensure that the lightweight items can be stored in the roof box.

Remember, your car can handle the extra load, but your roof box has its limitation. Keeping an eye on the weight limit for your roof box will ensure the stability of your car when moving.

3. Pack Longer Items In A Roof Box Cargo Carrier

Roof boxes are available in many different sizes, so choose one large enough to fit all of your long items.

If you’re traveling with items like skis and snowboards, it’s a good idea to pack them in a roof box cargo carrier. This will keep them safe and secure while you’re on the road.

Many large roof boxes in the market, like Thule Pulse Alpine or Thule Motion, can easily accommodate 3-4 skis and 5-7 snowboards.

4. Put Your Suitcases In Your Roof Box Storage

Many roof boxes feature a special section on top specifically designed to store luggage. This can be a great way to keep your suitcases safe and secure while on the road. Plus, it can free up space in your car for other items.

If you’re traveling with a lot of luggage, choose the right roof box for carrying suitcases. This type of roof box is generally medium to high-profile, with a slightly taller dimension to accommodate a few larger suitcases.

In addition, they are designed to do the packing and unpacking much easier and keep your belongings safe and secure.

5. Distribute The Weight Evenly

When packing your roof box, it’s important to distribute the weight evenly. This will help ensure a smooth and quiet ride and prevent any items from sliding around. 

The best way to do this is by putting the heaviest items in the center of the roof box and balancing everything out as much as possible.

This might take a little time and effort, but it’s worth it in the end. Not only will your items be more secure, but you’ll also avoid any unpleasant noises while on the road.

6. Make Sure Your Roof Box Is Properly Secured

It’s important to ensure that your box and roof bars are fitted correctly and securely before hitting the open road. Check out our article about the best position for the roof box on a car.

The two most common mounting systems for roof boxes are u-shaped bolts and power click mounts, and your manual should include fitting instructions.

If you’re unsure how to fit your roof box, watch the video below.

7. Take Advantage Of Any Straps Or Holders

If your roof box comes with straps or holders, be sure to use them. This will help keep your items in place while you’re driving. In addition, it will help prevent the roof box from shifting around and becoming unstable. 

If your roof box doesn’t come with straps or holders, you can use bungee cords to secure it in place. Just be sure to tie them down tightly, so they don’t come loose while you’re on the road.

8. Wrap Things In Plastic

When packing your roof box, wrapping items in plastic is a good idea. This will help keep them dry and protected from the elements. In addition, it can help prevent them from getting scratched or damaged while you’re driving.

There are a few different ways to do this. You can use large garbage bags, which are cheap and easy to find, or purchase special packing blankets or sheets designed for this purpose.

Whichever method you choose, be sure to cover everything in plastic, so it’s well-protected.

9. Keep The Locking System Clear

The locking system is a very important component of the storage box. It needs to be sturdy and secure to feel confident about leaving your belongings in it.

When you pack your items into the box, you must ensure that your belongings don’t block or obstruct the locking system when closed. 

When you don’t ensure the locking system is clear, your storage box may spring up as you drive down the road. 

So make sure that everything is packed neatly and that there is plenty of clearance around the locking system so it can do its job properly.

10. Get Somebody To Help You Load

Rooftop cargo boxes can be difficult to load from standing on the ground, so it’s best to get somebody to help you. One person can hand you the luggage while you stand on the floor of the backseat. 

You could also use a ladder or other tool to help you reach the top, giving you greater control and spending more time organizing your storage box for the best load.

11. Tie Down The Box For Extra Caution

As an extra precaution, you can tie down your rooftop box with straps or bungee cords. This will give you peace of mind that the box is securely attached to your roof.

The box should be reliably secured, but if you want that added protection, don’t hesitate to throw some straps across it after you have loaded everything in.

Make sure to use quality straps or cords that can withstand the weight of the box and whatever you put inside it. And don’t forget to check the tension now and then, especially if you’re on a long road trip. 

You don’t want your belongings flying all over the highway in a sudden gust of wind.

12. Finally, Drive Safely

Now that you have all your items packed safely in your roof box, it’s time to hit the open road.

But before you do, be sure to take a few minutes to drive around and get used to the extra weight. It may feel a bit different at first, but with a little practice, you should be able to handle it like a pro.

And most importantly, remember to drive safely. The last thing you want is an accident because you weren’t paying attention to the road. So take your time, be patient, and enjoy the ride.

Conclusion

Now that you know how to pack your roof box for a road trip, all that’s left is to hit the open road. Take advantage of our tips for packing a roof box cargo carrier – it will make your life much easier. 

And be sure to drive safely to avoid any accidents on your trips. Enjoy your journey, and happy travels!

The post How to Pack a Roof Box For Your Next Road Trip [12 Essential Tips] appeared first on Family Road Trip.

If you’re planning on taking a road trip anytime soon, you might wonder if you can drive with an empty cargo box on your rooftop.

The answer is yes, as long as the box is secured correctly and you don’t exceed the speed limit. Empty roof boxes can be tricky to handle, but as long as you take the necessary precautions, you’ll be able to hit the open road with no problems.

This blog post will discuss why some people still keep an empty roof box on their cars all the time and seven reasons you shouldn’t follow their steps.

Hopefully, this post will answer your question.

Let’s dive in!

Why Do People Still Drive With An Empty Roof Box On A Car?

Like many, you’ve probably wondered whether keeping a cargo box on your car roof is worth it. After all, they can be pretty convenient for weekend getaways and spontaneous road trips.

We get it.

However, they can also be a pain when they’re not in use. You have to take them down, find a place to store them, and then put them back up when needed.

So, what’s the verdict? Is it worth it to keep a cargo box on your car roof? The short answer is NO, but it may depend on how often you use it.

If you only use it occasionally, it might not be worth the hassle of taking it down and putting it back up. However, if you use it frequently, like twice a week, the convenience may outweigh the inconvenience.

Ultimately, the decision is up to you. But if you decide to keep a cargo box on your car roof, invest in one that is durable and easy to use. That way, you can enjoy all the benefits without any headaches.

Now. Let’s examine why you shouldn’t keep an empty cargo box on your car roof.

7 Reasons You Shouldn’t Drive With An Empty Cargo Box

It may seem like no big deal to leave the cargo box on your roof when it’s not in use, but there are some good reasons why you shouldn’t do this.

Here are seven reasons to consider before leaving that empty box on your car roof rack:

Extra Wind Resistance

Extra wind resistance is one of the biggest reasons to avoid driving with an empty roof cargo box. The box can act like a sail and increase your car’s wind resistance when empty.

When you travel at a certain speed on the highway, the roof racks will make high whistling and humming noises.

The airflow meets the frontal part of the crossbar and cargo box. Then, it bypasses from above and below, and beyond the crossbar. The whistling noise from the roof rack is caused by wind passing over the box on top of your car.

Which one do you want to hear: wind noise or your music? It’s your choice!

Seriously Affect Fuel Consumption

Except for a fully electric car like the Tesla Y, driving with an empty roof cargo box increases your car’s fuel consumption.

The extra wind resistance will cause your vehicle to work harder, which means it will use more gas. You may argue that the cargo box is aerodynamically designed, but not all of them are.

Even if it is, the box will still increase your car’s wind resistance and drag. If you want to save money on gas, leave the cargo box.

It Creates A Lot Of Noises

The cargo box is designed to store and transport items, but when it is empty, it can be very noisy. You may not realize how much noise an empty cargo box (and roof rack) can create until you try driving with one.

If you’re driving on the highway, it can be even louder when you hit over 80 mph. The wind can create a lot of turbulence and noise inside the box.

Avoid driving with an empty cargo box if you’re looking for a quiet ride. Instead, check out our article about how to stop wind noise from the roof rack.

Overhead Clearance (Restriction)

One of the crucial things you need to be aware of is your car’s overhead clearance. Most cargo boxes are designed to fit snugly against the roof of your vehicle.

But if you have a taller vehicle like Honda CR-V or Toyota Highlander, you may need to take extra caution.

You know the “large box” on the car rooftop when going on a road trip with a cargo box. It constantly reminds you that you have potential restrictions on where you can go.

And what will happen when you don’t use a cargo box and don’t remove it? You tend to forget about it. And you will get into trouble when you go under a low bridge or into the parking of malls with low raised roofs.

You will be fortunate if you only get minor scratches on the box. But unfortunately, it is more likely that you will cause severe damage to your car and possibly injure yourself.

So, always remove your cargo box when you’re not using it.

It Affects Your Car Handling

It’s not just the wind resistance and fuel consumption that you need to worry about when driving with an empty roof cargo box.

There is also the issue of safety.

An empty cargo box can be dangerous because it can become unbalanced and wobble. In addition, it can affect your car handling, making your car harder to control. Finally, if it happens at the wrong time, it could cause an accident.

So, if you’re going to drive with an empty roof cargo box, secure it properly. Otherwise, it’s best to leave it at home and store it in a garage.

They Are Expensive And Easy Targets For Thieves

Roof boxes and roof racks are expensive. An empty roof box is an easy target for thieves. They will see it and think that there might be something valuable inside.

Even if there is nothing inside, they can still cause damage to your car by trying to break into it. That is why it is essential to take measures to prevent this.

One way to do this is to remove the roof box when you are not using it. It might not be convenient, but it is the best way to ensure that your belongings are safe.

If you must leave the roof box on your car, ensure it is locked and secured. You can also try to park in a well-lit area or close to security cameras.

Unnecessary Added Weight

There are many reasons to avoid carrying extra weight when you don’t have to, and cargo boxes are no exception. Not only does the weight affect your fuel economy, but it can also cause damage to your vehicle.

Tires, transmissions, suspensions, and other parts of your vehicle are designed to work with a certain amount of drag. When you add extra weight, it can throw off this delicate balance and cause problems.

In some cases, the damage caused by the extra weight can be costly to repair. Therefore, it’s always best to avoid carrying unnecessary weight, including an empty cargo box.

If you don’t need to use it, remove and leave it at home – your vehicle will thank you for it.

If You Don’t Plan To Remove Your Cargo Box, Here Are Some Tips…

As we’ve seen, there are some good reasons to take your cargo box off when you’re not using it. But if you don’t want the hassle of removing and attaching it every time, here are some tips to help you drive safely with an empty roof box.

• Make sure that the cargo box is properly secured before you start driving. Check that the box is not loose and that all the locks are engaged.

• A roof box is lightweight. Placing your spare tire helps weigh down the box and reduce the noise from wobbling.

• You can also try to drive slowly and carefully when you have an empty roof box. It will help to prevent any accidents from happening.

• Finally, be sure to check your insurance policy. Some policies may not cover damage caused by an empty cargo box.

Final Thoughts on Empty Cargo Boxes

Most people wouldn’t dream of driving with an empty roof box, but there are a few good reasons not to do it. First, an empty roof box can be extremely noisy, making it difficult to hear other traffic on the road.

An empty roof box can also be unstable, making it more likely to fly off your vehicle in high winds.

And finally, an accident while driving with an empty roof box could cause serious damage to your vehicle and the roof box itself.

So, think twice the next time you consider driving with an empty roof box!

Happy traveling!

The post Can You Drive With An Empty Cargo Box On Your Roof? And What Happens If You Do? appeared first on Family Road Trip.

The sunroof is a great feature to have in a vehicle. It allows you to enjoy the sun and view of the sky while driving. However, what about when you have a lot of cargo to carry; can you put a cargo bag on a sunroof?

Technically, the answer is yes, but we wouldn’t recommend it. Almost all roof bag manufacturers don’t recommend it because the glass is too weak to handle the pressure from the roof bag’s weight, and it will eventually break. 

In this article, we will go into more detail about why you shouldn’t put your cargo bag on a sunroof and provide the best solutions for carrying your items.

Can You Put A Cargo Bag On A Sunroof? NO! Here’s Why

Cargo bags were designed to go on top of a car with a flat, metal roof. Depending on how much weight you put on it, placing a cargo bag directly on your car’s sunroof is a bad idea.

On average, most vehicles without sunroofs can handle a maximum weight between 165 lbs to 180 lbs on the rooftop, depending on the type of car. [1]

But not for the car with a sunroof. So, how much weight can a sunroof hold?

There is no specific guideline on how much weight you can put on it. From a structural load perspective, you would probably be fine. But, many are against it.

A car sunroof is a thick reinforced glass designed to be part of the load-bearing body of the car. It can take a lot of punishment in a rollover or crush.

When there is added weight from a cargo bag, it can affect the rails and alignment, damaging the roof mechanism.

In addition, it creates unnecessary stress on the hinges and seals of your sunroof, which may cause it to break or leak in the future.

If you are driving on undulated roads, one hard bump could cause any heavy object in your cargo bag to come crashing down on the moonroof, shattering it.

It’s tempered glass. Once it fails, it fails big time. Normally by raining down glass chunks on your head. Sunroof replacement is very expensive. I’m talking about a few thousands dollar to replace it.

Some of the car dealers won’t bother to repair it.

What Are The Best Solutions To Put A Roof Bag On A Sunroof?

There are three ways you can put a roof bag on a sunroof.

Slide The Cargo Bag To The Rear

If you drive a large car with a fixed sunroof, there is a bit of space to the rear of the sunroof. So you can slide the rear rail back and tie the straps to the bag.

Packing your heavy items towards the rear minimizes the sunroof’s contact area. However, it would be best to pack light items of less than 40 lbs to reduce the chance of damaging your sunroof should there be movement from the bag while you are driving.

But the problem with this method is that some of the parts of the roof bag will still be resting on the sunroof. And, you should be concerned with the wind flapping the bag against the roof and damaging the sunroof and paint.

Use A Roof Basket

A roof basket is a great way to carry your cargo bag and utilize your car’s crossbars. It is easy to assemble and install to your roof rack with a couple of bolts.

The roof basket will protect your sunroof from direct contact with the cargo bag. It also gives you more space to store larger and heavier items.

And, you can still open or tilt your car’s sunroof and enjoy the trip. The downside of a roof basket is that it creates noise and wind drag, slightly reducing your car’s fuel efficiency.

The price range of roof baskets is between $100 to $350, depending on the size and brand.

DIY Roof Rack

There is another option if you are on a very tight budget or don’t want to spend money on a roof rack.

If you are comfortable with tools and are a DIY person, why not make a roof rack yourself?

This option is not for everyone as it requires some technical skills. It will take some effort and time, but it can be done.

But, if you are up for the challenge, here are some instructions on how to make a roof rack.

1. You need two pieces of 1×1 sheet of plywood, quality felt strips, short wood screws, short bolts, washers, gorilla glue, rubber paint, and Velcro strips.
2. Cut the plywood wide enough that it doesn’t overhang the car but goes under the roof rails.
3. Make sure it goes right under the roof rails.
4. Drill out the plywood with a small paddle about 1.5 x 1.5 inches from each corner of the plywood.
5. Screw the plywood to the 1x1s. Make sure your screws don’t go through the bottom of the 1x1s.
6. Paint the rubber paint on all the wood surfaces (and on top of screws). It will make it nice looking but waterproof and resist damaging the vehicle.
7. After the paint dries, glue felt strips to the bottom of the 1x1s.
8. Cut small bolt-size holes in the Velcro.
9. Run bolt top through the washer, the rough side of Velcro (rough side face down), and the plywood hole.
10. Afterward, run smooth side through the bottom of the bolt, then the washer fastens with the nut.
11. Velcro all four holes to the plywood in this fashion, then Velcro to the roof rails.
12. Stick the cargo bag on the new roof rack, and it’s done! Congratulation to yourself!

The Long-Term Option: Invest In Cargo Box

We have discussed temporary methods to put a roof bag on a sunroof. But, of course, there are many other ways you can do to haul a cargo bag onto your car’s rooftop.

But, if you often go on road trips and carry a lot of stuff, investing in a cargo box that is elevated off your sunroof by a roof rack would be the best option.

A roof box is a lot more expensive than the methods above, but it has some significant advantages.

• It is more aerodynamic than a roof bag. As a result, it will not flap in the wind and create noise or drag, reducing your car’s fuel efficiency.
• A good quality cargo box is durable and can last for years with proper care. And you don’t have to worry about damaging your sunroof.
• Most of them come with a lock, so you don’t have to worry about stealing your belongings while away from the car. Whereas a cargo bag is easily cut through with a knife.
• Roof boxes are watertight. You will feel peace of mind knowing that your items are safe from rain and elements.
• They look cool on your car!

The primary con of the roof box is the price. They are not cheap, ranging from $200 to $1500 depending on size and brand.

So, Should You Use A Roof Bag With A Sunroof?

You can also DIY a roof rack to put the bag on top of your car if you’re tight on budget.

Of course, if you often go on road trips and carry a lot of stuff, investing in a cargo box would be the best option. It is more expensive than the roof bag, but it has some significant advantages, including better aerodynamics, durability, and security.

Happy road trip!

The post Best Roof Bag Carriers To Use With Sunroofs appeared first on Family Road Trip.

Are car top carriers safe? This is a question that I get asked a lot. And to be honest, it’s a valid concern. After all, you are putting your belongings on top of your car and strapping them down. That seems like it could be dangerous.

But rest assured, car top carriers are very safe when used correctly.  Car top carriers are designed to be aerodynamic and durable, but there are still some things you should keep in mind before hitting the open road.

Read on for tips on how to use a car-top carrier safely.

What Are Car Top Carriers?

Car top carriers are racks attached to your car’s roof, such as cargo boxes, cargo bags, ski racks, kayak roof racks, bike roof racks, etc. They are used to store large items, such as luggage, camping gear, or sports equipment.

Car top carriers come in various shapes and sizes, and there is a model that will fit nearly any car (see our guide below to research by car type!)

Most car top carriers are made out of durable materials, such as ABS plastic, aluminum, or steel. The carrier’s frame is typically attached to your car’s roof rack using straps, clamps, or bolts.

The carrier is usually made of waterproof and UV-resistant materials, such as PVC or polyester. This helps to protect your belongings from the elements.

Why Are Car Top Carriers Safe To Use?

One of the main reasons car top carriers are safe to use is that they are designed to be aerodynamic. This means that they will not slow down your car or create drag while you’re driving.

Cargo boxes reduce wind noise and drag on your car because of their aerodynamic designs.

Thule and Yakima are two well-known manufacturers of bike racks, tail lights, and other various accessories that are designed to keep you safe on the road.

They’re continuously developing their technologies to ensure all the rooftop carriers they made are safe for road users.

In addition, you can secure the top carriers to your car with straps, so they do not fly off while you’re on the road.

When used correctly, car top carriers can provide extra storage space without compromising your family’s or belongings’ safety.

Even if you’re car is not fitted with roof rails, there are car top carrier solutions you can use – we’d just caution on using these methods if your car has a sunroof.

How Do You Know If A Car-Top Carrier Is Safe To Use?

When choosing a car-top carrier, it is important to ensure that it is the right size and type for your car.

You will want to choose a smaller carrier if you have a smaller car, such as a sedan or hatchback. You can choose a larger carrier if you have a larger car, such as an SUV or van.

It is also important to ensure that the carrier you choose is compatible with your car’s roof rack. Most car top carriers will list what types of roof racks they are compatible with on their website or product description.

If you’re unsure what size or type of car-top carrier to choose, you can always consult a professional.

8 Tips For Using A Car-Top Carrier Safely

Now that you know a little bit more about car top carriers and how to choose the right one for your car, let’s talk about how to use them safely.

Here are eight tips for using a car-top carrier:

1. Make Sure That You Use A Car-Top Carrier That Is Designed For Your Vehicle.

One of the most important things to remember when using a car-top carrier is to make sure you use one designed for your vehicle.

Each car-top carrier is designed for a specific type and size of vehicle. If you try to use a carrier not designed for your car, you risk damaging your car or the carrier itself.

Consult the car-top carrier’s website or product description to ensure that it is compatible with your vehicle.

2. Make Sure That The Cargo Bag Is Properly Inflated.

One of the most important things when using a car-top carrier is ensuring that the cargo bag is properly inflated.

This will help keep your belongings safe and secure while driving. If the bag is not properly inflated, it could come loose and cause an accident.

3. Do Not Exceed The Weight Capacity Of Your Vehicle

It is important to ensure that the carrier’s weight does not exceed your vehicle’s weight capacity. This can be done by checking the manufacturer’s specifications or consulting a dealer.

Exceeding the weight capacity can cause damage to your car and may lead to an accident.

4. Make Sure That The Carrier Is Properly Secured To Your Car Before You Start Driving.

The last thing you want is for the carrier to come loose and fly off your car while driving. This could not only damage your car, but it could also cause an accident.

To avoid this, ensure the carrier is securely fastened to your car before you hit the road.

5. Don’t Overload The Carrier

Do not overload your car with a top carrier. Overloading your cargo box can cause the carrier to topple over; worse, your belongings could fly out and cause an accident.

It’s important to check the carrier’s weight limit and ensure you don’t exceed it. Make sure you distribute the weight evenly and don’t exceed the weight limit of the carrier.

If your cargo is overloaded, it can cause the carrier to become unbalanced and could lead to an accident.

Learn how to properly pack a roof box before you hit on the road.

6. Check The Weather Forecast

Check the weather forecast before heading out on your trip. If there is bad weather in the forecast, it is best to delay your trip or find another way to transport your belongings.

7. Pack Heavier Items First

Pack heavier items closer to the center of the carrier. This will help to keep your car balanced and stable. If you are transporting a lot of heavy items, it is also a good idea to distribute the weight evenly between the front and back of your car.

8. Tie Down Your Stuff Inside

Do not forget to secure your belongings inside the carrier. Most carriers have a zipper or velcro closure that will help to keep your belongings safe and secure.

You can also use additional straps or bungee cords to help tie down your belongings.
