Biggest Roof Cargo Boxes with the Largest Capacity: Even while most automobiles have cargo capacity, it may not be enough to transport all your belongings, especially if you have children or pets or if you go camping or skiing. 

Building a rooftop cargo box may be necessary to improve storage capacity, which is a more cost-effective solution than replacing the vehicle entirely.

A rooftop cargo carrier can ease visit flood troubles while pressing for a camping get-away, cross-country outings, or migration for drivers who require more storage than a vehicle’s insides can give. 

Both hard-shelled cargo and delicate rooftop sacks are outlined to keep cargo secure from intrusive thieves, whereas moreover securing things from cruel climate and street rottenness.

When not in use, a soft rooftop cargo carrier is lighter in weight, easier to mount to a vehicle’s roof, and can be rapidly stowed. 

Simple tie-down systems with adjustable straps, robust hooks, and zippered pockets can be loaded on top of even a naked roof without the use of rack systems. Many soft cargo carriers have watertight seams that are welded or taped.

A difficult rooftop cargo carrier, too known as a roof cargo box, requires crossbars and a roof rack framework. In spite of the fact that they are more costly and more troublesome to utilize, they give more noteworthy security for high-value things such as skis, snowboards, or other open-air gear utilized for camping or bicycling. 

The vigorous outside shells are not a chance of being broken by pressing products with sharp edges or elliptical shapes since most contain locking mechanisms.

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 in spite of the fact that numerous of the best-rated items are made of strong and weatherproof materials, they can still break or drop separated at the creases. 

Roof boxes are heavier and require extra hardware, influencing the execution of a vehicle. Both assortments have a strong plan that will decrease fuel economy. A few roof boxes are outlined to be more aerodynamic.

Here are some of the Biggest Roof Cargo Boxes on the market for your consideration

Sport Rack Vista XL Rear Opening Cargo Box – Best Roof Cargo Box

The sport Rack Vista XL Raise Opening Cargo Box is one of the largest roof cargo box on the market. It has an 18-cubic-foot capacity and fits square, circular, and most plant roof racks.

With tool-free mounting options, the sport Rack Vista XL may be reached from either side or the back of a car, making it simple to grab items from a variety of positions.

The sport Rack Vista XL is UV-resistant and long-lasting, thanks to its ABS structure. The sport Rack Vista XL is 63 inches long, 38 inches wide, and 19 inches tall, and it can hold up to 100 pounds of baggage.

Thule Pulse Medium Rooftop Cargo Box

The Thule Pulse Medium is a 67-inch long, 33-inch wide, and 16-inch-high rooftop freight carrier that can be opened with one hand for quick loading and unloading.

The addition of a central locking system improves security. For snow-filled activities, this unit contains 14 cubic feet of storage and can fit a few sets of skis (up to 155 cm) or three to four snowboards.

Thule Force XT Rooftop Cargo Box

Made from a durable finish, this versatile roof-mounted cargo box can hold up to 165 pounds.

The Thule Force XT is designed to fit a wide array of vehicles. Its clever quick-mount system clicks into place when the box is secure and tightened, ensuring a proper fit.

Additionally, a dual-sided lockable compartment allows for security and easy unloading when needed. The 18-cubic-foot Thule Force XT can hold up to five to seven pairs of skis or three to four snowboards.

If the high-end Motion doesn’t pique your interest, you’ll have to choose between the Force XT and the Yakima Skybox.

Both models reflect the ideal middle ground for many users, although we give the Yakima a slight advantage for a few minor reasons.

To begin with, we love its latching design, which has a wide handle that opens and closes the box independently of the locking mechanism.

Sport Rack Horizon Alpine Cargo Box

This rooftop cargo carrier is made of impact-resistant ABS material and fits square, round, and most factory racks. This is one of the best roof box for camping. You’ll love its convenience when you go camping with it.

It includes a centralized locking mechanism and a passenger-side aperture for cargo access that doesn’t obstruct traffic. 

The sport Rack Horizon Alpine Luggage Box can store five to six pairs of skis (up to 180 cm) or three to four snowboards while carrying other cargo or camping supplies.

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. 

The Fivklemnz soft rooftop cargo carrier is a best-seller in the marketplace, accommodating everything from multiple suitcases to a full camp setup with sleeping bags and a tent. 

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.

Cargo Carrier Thule Motion XT XXL

For large loads, Motion XT XXL is the best option. It has a storage capacity of 22 cubic feet and a total load capacity of 165 pounds.

It also comes with the Power Click quick-mounting mechanism, which makes installation simple and secure.

The Motion XT XXL stands out with a professional fit and finish and two-color options.

Thule Force Cargo Box

This carrier is available in a variety of capacities, ranging from 13 cubic feet to more than 21 cubic feet.

It offers incredible qualities including opening on both sides, being simple to install, and having a built-in lock for protection.

It can also be put on any sort of roof rack, regardless of manufacturer.

Carbonite Skybox by Yakima

The Carbonite Skybox by Yakima is among the biggest roof box family. It has a volume of 21 cubic feet and a load capacity of 28 kilograms, as well as a dual-sided opening and a super latch system.

Its most appealing characteristic is that it can be installed without the use of any equipment, making it extremely user-friendly.

It has a long, streamlined form with an aerodynamic element that reduces wind noise and drag. The box also has a locking cover to keep it safe from theft.

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 $599 for the 16-cubic-foot model ($649 for the 18-cubic-foot model), you get robust storage for your goods as well as 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).

RoofPax Car Roof Bag and Rooftop Cargo Carrier

The RoofPax soft rooftop cargo carrier is big roof box than others and is amongst the best cargo box with a capacity of 19 cubic feet.

It’s built of tough materials and features 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 it can be used with or without roof rails.

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

There’s also a smaller 15 cubic-foot bag that extends to the same height but has a smaller footprint (43.3 inches long and 33.5 inches wide).

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. 

Many of these versions 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 vans.

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.

The INNO is the most low-profile rooftop box on the market, but there are a few versions that 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 $500 less.

Marksign Truck Cargo Bag with Cargo Net

So, technically, this isn’t a cargo crate. However, with a capacity of 26 cubic feet, we couldn’t pass up Marksign’s colossal alternative.

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.

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 take a measurement from the back hatch to the middle of the front crossbar of the vehicle.

That distance must be greater than the cargo box’s hatch clearance, as indicated on the manufacturer’s website. You’ll also want to make sure 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 with 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.

Skis, paddles, golf clubs, and strollers, for example, will require a larger box; ensure sure 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 gear capacity in cubic feet 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.


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. It’s easier and safer to stow your heaviest items inside the vehicle, such as a fully loaded cooler. 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 features 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.
