10 Best Hard Top Cargo Carriers 2026 in the United States

The Thule Motion 3 XXL Rooftop Cargo Box offers a spacious solution for those in need of additional vehicle storage. Its standout feature is the 21 cubic feet of storage space, making it ideal for long trips or when transporting bulky items. The aerodynamic design, with its wing-shaped profile, aids in reducing drag, potentially improving fuel efficiency during travel.

One of the significant advantages of this cargo box is its user-friendly installation. The PowerClick quick-mount system simplifies attachment to the vehicle roof, with a torque indicator that ensures a secure fit. Additionally, the SlideLock system provides added security by automatically locking the lid in place and indicating when the box is securely closed. This serves as a reassurance that your items are safe.

However, it's worth noting that the box is not water-resistant, which could be a drawback in adverse weather conditions. The one-handed opening and closing mechanism, along with included locks, enhance the user experience by making access easy while keeping contents secure. The material used is aluminum, contributing to durability, although the large size and weight (35 kilograms) might make handling a challenge for some users. Despite this, its compatibility with a wide range of vehicles makes it a versatile choice for many. The lack of water resistance might require users to take additional precautions for weather-proofing. With a strong reputation and positive customer ratings, this Thule cargo box appeals to those who prioritize space and ease of use, especially on longer journeys.

The Thule Motion 3 XL is a spacious hard-top cargo carrier offering 16 cubic feet of storage, which is suitable for families or users needing extra room for road trips. Its wing-shaped profile with a forward-leaning nose improves aerodynamics, helping to reduce drag and potentially save fuel compared to boxier carriers. Installation is straightforward thanks to the PowerClick quick-mount system that signals when the carrier is securely attached, making setup easier and faster for most users. The SlideLock system provides separate locking and opening functions with an indicator for secure closure, enhancing security and peace of mind during travel. The aluminum shell promises good durability, though it is noted as not water resistant, so some caution might be needed in heavy rain or snow conditions. Compatibility is broad due to its universal fit, but users should verify roof rack suitability given the carrier's size (88"L x 39"H).

The sturdy lid with a wide handle allows one-handed operation, adding convenience. While the carrier is relatively lightweight at 8 pounds, the mostly aluminum build balances durability with ease of handling. Available accessories like interior lighting and protective liners add practical value but come separately. This carrier is ideal for those looking for a reliable, large-capacity rooftop box that combines aerodynamic design with secure, easy mounting, although extra attention may be necessary in harsh weather due to its limited water resistance.

The Thule Force 3 XXL is a spacious hard-top cargo carrier, offering 21 cubic feet of storage which makes it suitable for large families, road trips, or anyone needing extra cargo space on SUVs, trucks, cars, and electric vehicles. Its aerodynamic shape helps reduce wind resistance and noise while driving, which benefits fuel efficiency and comfort. Installation is straightforward and tool-free, featuring a mounting system that confirms when the box is securely attached with a clear click, making it easy even for first-time users.

The dual-sided opening adds convenience by allowing access from either side of the vehicle, which can be handy in tight parking spots. Security is well-covered with Thule's SlideLock system, which automatically locks the lid and signals when it is properly closed, helping to keep belongings safe from theft or accidental opening. Made from durable plastic, the box is weatherproof and designed to handle regular use and rough conditions, ensuring it will last over time.

The size and compatibility are excellent for a wide range of vehicles, although at 53.5 pounds, it is somewhat heavy to handle during installation. The Thule Force 3 XXL serves as a reliable and user-friendly option for those looking to increase their vehicle’s cargo capacity with a secure, easy-to-install, and durable hard-shell carrier.
