No matter how well we plan, we usually end up taking entirely too much things with us on vacations and athletic trips.

We “want” to take everything, even if it won’t fit in the vehicle. And our car has to comfortably seat five individuals.

The question is, how do you keep it all together? A large, capacious shipping container is the correct answer.

All of your bags and sports gear may fit in the cargo compartment. It mounts easily to the top of your automobile, making room in the back of the truck for extra cargo.

It also means no one in your group will need to hold onto anything, which makes for a more relaxed and secure trip for everyone.

This article provides a comprehensive overview of the largest cargo boxes on the market, allowing you to bring everything you need on your next trip.

Our Top 5 Largest Roof Boxes

Thule Motion XT Rooftop Cargo Carrier

Thule Motion XT Rooftop Cargo Carrier

The Thule Motion XT is the perfect choice for anyone looking for a high-quality, reliable rooftop cargo carrier.

This carrier provides an impressive 22 cubic feet of additional packing space, making it perfect for longer trips or carrying larger items.

The Motion XT is also designed for optimal space efficiency and aerodynamics, so you can be sure it will fit your car perfectly and help reduce fuel consumption.

Additionally, the quick-mount system ensures that the box is securely mounted to your roof, while the dual-side opening allows for quick and easy access from either side of the vehicle. The lid also automatically locks in place, providing peace of mind that your belongings are safe and secure.

Thule Force Cargo Box - What are the biggest type of roof boxes you can get?

Thule Force Cargo Box, Black

This is again another fantastic item from Thule, and it looks well and works much better. Due to the complexity of the mounting procedure, however, we have ranked this second.

Cargo containers are installed on roof rails in the middle of the vehicle once the mounting hardware is released. This process is a bit more tedious and exacting than the average. Setup nevertheless required no more than 5 minutes of your time. And the only drawback was this.

The box has a quick-grip mounting method built in, so there was no need for any tools during the installation. The AeroSkin cover, with its diamond-like structure, is very sturdy. The aerodynamic form has the dual benefits of being both quiet and easy on the eyes.

With the large SecureLock, you can be certain that the container will stay safely closed. Because of the vehicle’s unique design, you can get to your belongings quickly and conveniently from either side.

YAKIMA - SkyBox Aerodynamic Rooftop Cargo Box

Yakima Carbonite Skybox

This massive, 21-cubic-foot freight container is quite heavy at 75 pounds. Weight capacity is very inadequate for its size at only 28 kg. The Thule versions, which have a capacity of 21 cubic feet, can carry far more cargo.

The product also includes an aperture on both sides, in addition to a super latch that makes opening and shutting the product very simple. Its sleek, streamlined profile makes a quieter and more comfortable ride. There are no tools required to set up this product.

To set up, just follow these steps:

  • To access the contents, lift the cover
  • Remove the restraints
  • The thumbwheels should be loosened
  • Place the roof box on the crossbars of your roof rack
  • Pull it back and the clamps will catch on the load bars
  • Put some pressure on the thumbwheels
  • Then clamp the levers shut

Seem simple enough? Once it’s in place, the box shouldn’t move around on the bars. If it begins to slide, you may prevent further movement by opening the cargo bay and tightening the associated levers.

Given that the Skybox is priced similarly to the Thule, there is no need to even consider the latter option. We took note of the reinforced lid stiffeners on the storage container.

Comparatively, we found mounting to be easier than with the Thule, albeit it still took only a few minutes. Thus, there are more benefits.

Modula Racks Travel Twin Silver 650 Litre Roof Top Cargo Box _

Modula Racks Travel Twin Silver 650 Litre Roof Top Cargo Box

The volume of its cargo hold is 650 liters, which is close to 23 cubic feet. It also has a 5-year warranty, which is comforting given that it costs a bit more than the earlier models we’ve looked at.

It is compatible with the vast majority of aftermarket and OEM roof-rack cross-bars, such as those manufactured by Rhino-Rack, Modula, Thule, Yakima, and Sport-Rack. This spacious cargo container is equipped with many of the features desirable in such containers.

First, there is a lockable lid that can be opened from both sides of the car, making it convenient for loading and unloading. The innovative quick-release legs of a Modular Rack make assembly and disassembly a breeze even for one person.

Having high-quality hinge hardware ensures that the item opens and shuts effortlessly every time. The strong acrylic top has been enhanced for durability. Applying regular auto maintenance items can keep your box looking like new for years to come.

Waterproof Truck Cargo Bag

Truck Cargo Bag with Cargo Net by Marksign

So, technically, this isn’t a roof box. But we just couldn’t pass up Marksign’s enormous 26-cubic-foot offering.

It’s a whopping 130 x 100 x 55cm in size (or 51 x 40 x 22 inches), so it should be able to fit just about everything you’ll need on your trip. You can put this on the back of any vehicle with ease.

This device includes four sturdy rubber grips for portability. After checking out the competition, we settled on this product because of how user-friendly it was. Each bag is supplied with a sturdy bungee net that measures 4 feet by 6 feet to keep it in place on your vehicle and protect your belongings from the elements.

The net can be extended to a size of 8 by 12 feet, making it ideal for use while driving. Marksign also comes with a total of 12 metal carabiners of varying sizes and strengths for safe and reliable tethering.

The cargo truck bed bag is made of 500D tarpaulin that has been electrically bonded together without any microscopic holes to prevent water from entering. The zipper has a vinyl covering. You can prevent water from getting in via the seals’ velcro-fastened flaps.

Since the fabric is resistant to the effects of sunlight, it should hold up well over time. The additional drawstring bags for stowing the cargo bag and net are a nice touch.

This is the finest truck-mounted cargo box available. If you’re in need of some more storage space and can swing the price, this cargo bag could be a good option, but keep in mind that a patent hasn’t yet been filed for it.

Parting Thoughts

We believe them to be the finest larges cargo boxes available, providing enough room for all of your travel necessities.

Consider if you will have access to another set of hands to assist you in mounting or removing the accessory from your car. You should think about how much your desired equipment weighs, too.

Before you jam all of your belongings into a carg and then onto the roof of your car, be sure to verify the weight restriction of both your roof and the roof rack of your vehicle and use the one that is lower. The car’s safety is your first priority.
