10 Best Roof Top Cargo Carriers 2026 in the United States

The Thule Motion 3 XL is a spacious rooftop cargo carrier with an 18 cubic feet capacity, making it suitable for families or travelers needing extra storage space. Its aluminum shell offers a sturdy and lightweight design, which helps keep the carrier durable without adding too much weight on your vehicle. Measuring 88 inches long, 18 inches wide, and 39 inches high, it fits most vehicles thanks to its universal roof mount system. The PowerClick quick-mount system is a standout feature, giving you an easy and secure installation with a helpful torque indicator that 'clicks' when properly tightened. Aerodynamics are well addressed with a wing-shaped, forward-leaning nose, which helps reduce drag and can improve fuel efficiency during travel. Security is also thoughtfully designed: the SlideLock system separates locking and opening functions, automatically securing the lid while providing clear feedback when it's properly closed. The sturdy lid with a wide handle makes loading and unloading simple, even with one hand.

Although it's not water-resistant, its solid construction should protect most belongings from light rain or splashes. The option to add accessories like interior lighting and protective liners adds convenience but may come at extra cost. The Thule Motion 3 XL represents a strong choice for those wanting a reliable, spacious, and easy-to-use hard-shell rooftop carrier, though if you need full weatherproofing, you might want to consider other models.

The Thule Force 3 Size L rooftop cargo box is a solid choice if you need extra storage space on your SUV, truck, car, or electric vehicle. With 11 cubic feet of capacity and dimensions of about 75 x 25 x 17 inches, it offers a moderately narrow design that fits well on most vehicles without being overly bulky. It weighs around 31 pounds, which is manageable for installation but sturdy enough to last. Made from durable plastic, this box is weatherproof, keeping your gear dry in rain or snow.

One of its standout features is the dual-sided opening, making it easy to load and unload from either side of your vehicle—a nice convenience when parked in tight spots. The mounting system is user-friendly with a clear click to confirm the box is securely attached, reducing installation guesswork. Security is well supported by the SlideLock system, which locks automatically and shows when the box is properly closed. The aerodynamic shape helps reduce wind resistance and noise, which is important for fuel efficiency and a quieter ride.

This rooftop carrier is well regarded by users, though some might find the size limiting for carrying very bulky items, and its price could be higher than simpler models. For those needing a reliable, versatile, and weatherproof rooftop carrier with good security and convenience features, the Thule Force 3 presents a balanced solution.

The Thule Force 3 XXL rooftop cargo box is a solid choice if you need plenty of extra storage on your vehicle. With a roomy 21 cubic feet capacity and large dimensions (about 91.4 x 35.2 x 17.9 inches), it can carry sizable gear for family trips or outdoor adventures. It supports a good weight limit typical for rooftop carriers, and its plastic shell is designed to be durable and weather resistant, helping protect your belongings from rain and road grime. One of its standout features is the dual-sided opening, which makes loading and unloading much easier because you can access your cargo from either side of your vehicle. The mounting system is tool-free and user-friendly, with a click indicator that confirms the box is securely attached—this adds peace of mind and saves time when installing or removing the carrier. Additionally, the SlideLock system enhances security by locking the lid in place and signaling when it's properly closed, discouraging theft.

The aerodynamic design helps reduce wind noise and drag compared to bulkier boxes, which is helpful for fuel efficiency during long drives. On the downside, the unit weighs about 53.5 pounds, making it a bit heavy to handle alone, especially during installation. Also, while it fits most SUVs, trucks, cars, and EVs, its size might be too large for smaller vehicles or tight parking spaces. For those seeking a reliable, spacious, and easy-to-use rooftop cargo box that balances convenience with strong build quality, the Thule Force 3 XXL is a highly recommended option.
