10 Best Car Top Cargo Carriers 2025 in the United States

The Thule Motion 3 XXL rooftop cargo box is a spacious and well-designed carrier ideal for families or anyone needing extra storage space on top of their vehicle. It offers a generous 21 cubic feet capacity and can hold up to 165 pounds, which suits most gear from luggage to sports equipment. Measuring about 96 by 39 by 20 inches, it’s quite large, so make sure your vehicle can accommodate its size. The box is made from durable aluminum, providing a strong and lightweight shell that helps protect your items. Its aerodynamic, wing-shaped design with a forward-leaning nose reduces wind drag, which can help improve fuel efficiency compared to bulkier carriers.

Mounting is straightforward thanks to the PowerClick quick-mount system, which signals when it’s securely attached, making installation faster and tool-free. Opening and closing the lid is easy with one hand, aided by a sturdy lid and wide handle, which adds convenience when loading or unloading. The SlideLock system enhances security by automatically locking the lid and showing when it’s properly closed, giving peace of mind that your belongings are safe. However, the box isn’t water resistant, so it’s best used in dry conditions or with waterproof bags inside. At 35 kilograms (about 77 pounds), it’s relatively heavy for installation, so some users may need assistance mounting it.

The box comes in a neutral titan color and offers optional accessories like interior lighting and protective liners, which are sold separately. This rooftop box represents a strong choice for anyone wanting a large, secure, and aerodynamic cargo carrier, especially if easy mounting and reliable locking are priorities.
