10 Best Rooftop Cargo Boxes 2026 in the United States

The Yakima SkyBox NX XL is a hard shell rooftop cargo box offering a spacious 18 cubic feet of storage, which can comfortably fit gear for up to four campers or long items like skis and snowboards up to 195 cm. It weighs 53 pounds, which is moderate and should be manageable for most users when installing it on the roof. The box is made of durable plastic with a sleek, nano-textured finish designed to resist scratches and wear, though it is not water resistant, so protection from heavy rain or water exposure could be a concern.

One of its standout features is the dual-sided access, allowing you to load and unload from either side of the vehicle, making it very convenient especially in tight parking spaces. The full metal handle and SKS lock provide solid security for your belongings and help lock the box to the vehicle, giving peace of mind during travel. The mounting system is roof-mounted, typical for this type of product.

Aerodynamically, while the product brief does not detail wind resistance, the low-profile design and smooth surface suggest it aims to reduce drag, potentially minimizing impact on fuel economy. The flattened interior floor maximizes usable space inside, so you won’t lose room to awkward shapes or supports. The box is best suited for dry conditions or with additional waterproofing measures. The Yakima SkyBox NX XL is a great choice if you need large, secure, and easily accessible rooftop storage for camping or winter gear, though the weight and lack of water resistance should be considered when planning your trips.

The Thule Motion 3 XL rooftop cargo box is a strong contender for those looking for extra storage space while traveling. Its wing-shaped profile and forward-leaning nose design help reduce drag, which can contribute to better fuel efficiency—an important factor for long road trips. With a sturdy build made from aluminum, this cargo box offers durability and a weight capacity suitable for a range of items. The easy-to-use PowerClick quick-mount system with an integrated torque indicator makes installation simple and secure, a definite plus for users who might find rooftop mounting challenging.

Accessibility is well thought out, as the box features a wide handle that allows you to open and close it easily with one hand. It also has a SlideLock system that not only secures the lid but also indicates when it’s properly closed, giving peace of mind about safety.

A notable downside is that this box is not water-resistant, which could be a concern for those traveling in wet conditions or looking to store items that need protection from rain. Additionally, while the cargo box is spacious, its weight of 23 kilograms might be heavy for some users to lift onto their vehicles.

The JEGS Rooftop Cargo Carrier offers a substantial capacity of 18 cubic feet, making it ideal for families or individuals who need ample storage space for road trips or vacations. With a weight limit of 110 pounds, it can hold plenty of gear without overloading. The hard shell is made from HDPE plastic, which ensures durability and weather resistance, keeping your items safe and dry during travel. The aerodynamic design helps maintain fuel efficiency, which can be a concern with large cargo carriers.

Installation is user-friendly, requiring no tools, and includes clear instructions and all necessary mounting hardware. The rear opening makes loading and unloading convenient, though it might be a bit awkward for shorter vehicles. Security is a strong point, with a four-corner locking system and a front latch providing peace of mind.

At 35 pounds, the cargo carrier might be a bit heavy for some to handle on their own during installation. Additionally, the hard shell design doesn’t offer as much flexibility when it comes to storing oddly shaped items compared to soft-shell carriers. Despite this, the JEGS Rooftop Cargo Carrier is a solid choice for those needing reliable and secure rooftop storage. Made in the USA, it comes with a limited lifetime guarantee, reflecting confidence in its quality and longevity.
