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:
