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 Force 3 XL is a spacious hard-top cargo carrier offering 18 cubic feet of storage, making it a great choice for families or outdoor enthusiasts needing extra room on road trips. Its aerodynamic design helps reduce wind noise and drag, which can improve fuel efficiency compared to bulkier rooftop carriers. Installation is straightforward and tool-free, with a secure mounting system that clicks to confirm proper attachment, making it user-friendly even for those who might not be mechanically inclined.

The dual-sided opening is a standout feature, allowing easy access to your gear from either side of the vehicle without needing to unload everything. Security is well thought out, featuring a SlideLock system that automatically locks the lid and indicates when it’s properly closed, giving peace of mind against theft. Compatibility is broad—the carrier fits SUVs, trucks, cars, and electric vehicles thanks to its roof-mounted design and adjustable mounting hardware. Durability is supported by a weatherproof plastic shell that withstands daily use and rough conditions, plus it has been extensively tested by Thule for safety and reliability.

Weighing 66 pounds, it is somewhat heavy for installation, so lifting it onto the roof might require some effort or assistance. Additionally, it is water-resistant rather than fully waterproof, so in very heavy rain, you may want to ensure your cargo is inside protective bags. This combination of size, security, and ease of use makes the Thule Force 3 XL an excellent pick for those who want a reliable, hard-shell carrier for various vehicle types and outdoor adventures.

The Thule Force 3 (Size L) is a well-designed hard-top cargo box offering 11 cubic feet of storage, making it a solid choice for SUVs, trucks, cars, and electric vehicles that need extra rooftop space. Its narrow and aerodynamic shape helps reduce wind drag and noise during travel, which is great for keeping fuel efficiency in check. Installation is straightforward thanks to Thule's quick-mount system that clicks securely into place, and an indicator confirms when it's locked safely.

The dual-sided opening is a convenient feature, allowing easy access to your gear from either side of the vehicle.

Made from durable plastic and tested extensively for road safety and weather resistance, this box is built to last through daily use and various weather conditions. Weighing about 31 pounds, it’s manageable for most users to handle during installation.

While the size is ample for many needs, it might be limiting if you require larger carrying capacity. Also, its plastic material, while tough, might not appeal to those wanting a metal alternative. This cargo box is well suited for active individuals and families looking for a reliable, easy-to-use, and secure rooftop storage solution that blends durability with sleek design.
