10 Best Rooftop Cargo Carriers 2026 in the United States

The Thule Motion 3 XL is a hard-shell rooftop cargo carrier designed to add extra storage space on your vehicle, ideal for road trips or carrying bulky gear. It offers a spacious 16 cubic feet of capacity with dimensions of 88" long, 18" wide, and 39" high, which should fit a wide range of items. Made from lightweight aluminum, it weighs just 8 pounds, making installation and removal easier compared to heavier models. The design includes a wing-shaped profile and a forward-leaning nose that help reduce wind resistance, which can improve fuel efficiency during travel.

Mounting is user-friendly thanks to Thule’s PowerClick quick-mount system, which features a torque indicator that clicks to confirm secure attachment. This makes setup faster and gives peace of mind that the carrier is properly fixed. Security is enhanced by the SlideLock system, which automatically locks the lid and shows when it’s securely closed, helping protect your belongings. The sturdy lid with a wide handle allows for smooth one-handed opening. Accessories like an interior light, a protective liner, and a storage cover are available but sold separately.

The carrier is not water resistant, so in heavy rain or snow, some moisture might get inside. This rooftop box fits universally on most car roofs equipped with crossbars and comes with a limited lifetime warranty, reflecting Thule’s confidence in durability. The Thule Motion 3 XL combines roomy storage, lightweight construction, and ease of use, making it a solid choice for those needing extra cargo space without adding much weight or drag. While its lack of water resistance might be a downside in wet climates, the aerodynamic design and secure mounting systems offer significant benefits.

Made from durable plastic, it balances sturdiness with a sleek, aerodynamic design that helps reduce wind noise and drag during drives, improving fuel efficiency compared to bulkier alternatives.

The mounting system is user-friendly and tool-free, featuring a clear click indicator to confirm the box is securely attached—great if you want hassle-free setup. One standout convenience is its dual-sided opening, allowing easy access from either side of your vehicle, which speeds up loading and unloading. Security is well-handled by the SlideLock system, which automatically locks the lid and signals when it’s fully closed, giving peace of mind when leaving the car unattended. The weather-resistant design protects your cargo from rain and dust, suitable for various climates and conditions.

While the material is sturdy, it’s plastic rather than metal, so very heavy or sharp items should be packed carefully to avoid damage. The carrier is fairly lightweight for its size but adding heavy cargo will impact roof load limits, so always check your vehicle’s specifications.
