10 Best Roof Top Cargo Carriers 2026 in the United States

The Thule Motion 3 XXL is a spacious rooftop cargo box offering 21 cubic feet of storage, making it ideal for families or anyone needing extra room for gear on trips. It supports up to 165 pounds, which should cover most luggage or sports equipment loads. The box is made of aluminum, giving it a sturdy yet lightweight feel compared to some plastic alternatives. Its aerodynamic, wing-shaped design helps reduce wind drag, which can improve fuel efficiency and lower noise while driving. Mounting is straightforward thanks to the PowerClick quick-mount system, which clicks to confirm a secure fit without tools, saving time and effort. Security is well thought out with the SlideLock system that automatically locks the lid and shows when it’s safely closed, plus the included locks add peace of mind. The wide handle allows easy one-handed opening and closing, which is convenient when loading or unloading.

A downside is that it isn’t water-resistant, so in heavy rain, water might seep inside unless extra protection is used. Its large size and weight (about 35 kg) also mean it could be challenging to handle alone during installation or removal. This cargo box suits those who want a reliable, roomy, and aerodynamic storage solution on their roof, especially for long trips, but users should be prepared for the physical effort required when mounting it.

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.

On the downside, the unit weighs about 53.5 pounds, making it a bit heavy to handle alone, especially during installation.
