10 Best Rv Cargo Carriers 2026 in the United States

The Thule Motion 3 XXL is a large rooftop cargo box offering 21 cubic feet of storage and a strong 165-pound weight capacity, making it suitable for carrying plenty of gear on your RV or vehicle roof. Its aluminum material ensures a sturdy yet relatively lightweight build, while the aerodynamic wing-shaped design helps reduce wind drag, which can help save on fuel during long trips.

Mounting is simple and secure with Thule’s PowerClick quick-mount system, which provides clear feedback when properly attached, so you don’t have to second guess if it’s safely fixed. The box also features a SlideLock system that automatically locks the lid and shows when it is securely closed, adding a good layer of security along with included locks. Opening and closing is easy with a wide handle designed for one-handed use, which is convenient when loading or unloading quickly.

This model is not water resistant, so it may not fully protect your cargo from heavy rain or harsh weather conditions. The size and weight of the box might require some care during installation and removal, especially for less physically strong users. Accessories like interior lighting and protective liners are available but sold separately. This cargo box is a strong option if you need a large, secure, and easy-to-use rooftop carrier and generally drive in fair weather or can take extra care during rain.

The MaxxHaul 70275 Aluminum Hitch Mount Cargo Carrier is designed to fit 2-inch Class III and IV trailer receivers, making it a versatile choice for trucks, SUVs, vans, and RVs. It offers a strong 500-pound weight capacity, which is enough to carry most mobility devices like wheelchairs or scooters. With dimensions of about 53.5" long by 29.75" wide, and a slightly smaller inside basket size, it provides a spacious area to load equipment securely. One helpful feature is the folding 60" ramp, which makes loading and unloading heavy or wheeled items easier. The carrier is made from lightweight extruded aluminum, providing good rust and corrosion resistance, which is important for outdoor use and different weather conditions.

The aluminum construction also keeps the carrier relatively light at around 68 pounds, making installation and removal less of a hassle. It includes anchor points to tie down your cargo safely and reflectors to improve visibility on the road. The product does not include a locking mechanism, so for security, you might need to invest in additional locks to avoid theft. While it’s foldable for storage, the size can still be bulky when mounted or stored. This carrier is a practical solution if you need a durable, weather-resistant platform to transport mobility devices or other heavy cargo outside your vehicle, but keep in mind you’ll want to add extra locks for security.

The Thule Motion 3 LTitan is a hard-shell rooftop cargo carrier designed for users needing extra storage space on their vehicles, such as RV owners or travelers. Its large size (80 x 37.35 x 18 inches) offers a generous volume of around 450 liters, making it suitable for carrying bulky gear or luggage. The aluminum material ensures a sturdy yet lightweight build, which contributes to durability and helps with fuel efficiency thanks to its aerodynamic, wing-shaped design with a forward-leaning nose that reduces wind drag.

Installation is straightforward and secure with the PowerClick quick-mount system, which uses a torque indicator to confirm proper fitting, so you can be confident it’s safely attached. The SlideLock system adds a layer of security by automatically locking the lid and showing when it’s closed properly, helping to protect your belongings. While it is water-resistant rather than fully waterproof, this should be sufficient for most weather conditions, especially with an optional protective cover available. The lid’s wide handle allows for easy one-hand operation, which is convenient when loading or unloading.

The package weight is relatively heavy at 29 kilograms, which might require some effort to lift onto the roof. Its water resistance may not fully protect contents in very heavy rain or submersion situations. This cargo carrier is a strong choice for those looking for a durable, secure, and aerodynamic roof box with easy installation, ideal for road trips and outdoor activities needing extra cargo space.
