10 Best Rooftop Cargo Boxes 2025 in the United States

The Thule 614 Pulse Cargo Box is a solid choice if you need extra storage space on your vehicle’s roof. It offers 14 cubic feet of capacity, which is enough for gear like 3 to 5 snowboards or luggage for a family trip. At 34 pounds, it’s lightweight enough to handle but still feels sturdy thanks to its hard plastic shell, designed to protect your belongings from weather and road conditions. The box is water-resistant, so your stuff stays dry during rain or snow. Setting it up is quick and easy with the FastGrip mounting system, which securely clamps onto most roof racks without requiring extra tools.

Loading and unloading is more convenient because the box opens from the passenger side, allowing better access in tight parking spots. Security isn’t overlooked either—the central locking system keeps the box tightly shut, and the special Thule Comfort Key only comes out when all locks are properly engaged, giving peace of mind against theft. Its aerodynamic shape helps reduce wind noise and drag while driving, although being 16 inches high means it adds some height to your vehicle, so you should be mindful of low clearances like garages. The 110-pound weight limit suits most typical cargo loads but might be limiting if you need to carry very heavy gear.

This cargo box is well suited for outdoor enthusiasts and families looking for durable, convenient rooftop storage that balances ease of use with security.

The Thule Motion 3 XXL rooftop cargo box is an excellent choice for those needing a large, durable storage solution for road trips or outdoor gear. It offers a roomy 21 cubic feet of space, capable of carrying up to 165 pounds, which makes it suitable for bulky items like camping equipment or luggage. The aluminum construction provides strength and a premium feel, although it is not fully water resistant, so it is best suited for dry or light weather conditions.

Its aerodynamic, wing-shaped design helps reduce wind drag, potentially improving fuel efficiency compared to boxier models. Mounting the box is hassle-free thanks to the PowerClick quick-mount system, which signals when the box is securely attached, offering a tool-free setup that is convenient for occasional users. The lid opens and closes smoothly with one hand, aided by a wide handle, simplifying loading and unloading. Security is enhanced with the SlideLock system that locks the lid tightly and clearly indicates when it’s secured, providing peace of mind when leaving your vehicle unattended.

Additional features such as optional interior lighting and protective liners enhance usability but may increase the overall cost. The cargo box is relatively heavy (about 35 kg), which may make installation challenging for one person. While it does not offer full water resistance, it is solidly built and comes with a limited lifetime warranty. This rooftop carrier is ideal for travelers and families seeking a spacious, secure, and sleek storage solution with easy mounting and access; however, those frequently driving in heavy rain or requiring complete waterproofing might prefer other options.

The Thule Force 3 (Size M) rooftop cargo box offers a solid balance of practicality and quality for anyone looking to expand their vehicle’s storage space. With 14 cubic feet of capacity, it’s a good fit for small families or individuals needing extra room for gear on trips. The box weighs about 32.6 pounds, which is manageable when installing or removing it. Made from durable plastic, it’s designed to withstand daily use and various weather conditions, though it’s water-resistant rather than fully waterproof, so some care around heavy rain is advisable.

Aerodynamics play an important role in minimizing wind noise and drag while driving, and this model features a sleek shape that helps keep the ride quieter and more fuel-efficient compared to boxier designs. The mounting system is user-friendly with a tool-free install and a clear click indicator, making it easy to attach securely even if you’re not handy with tools. Accessibility is enhanced by the dual-sided opening, letting you load or unload cargo from either side of your car, which is very convenient in tight parking spaces.

Security is handled well with the SlideLock system, which automatically locks the lid and shows when it’s securely closed, giving peace of mind when you leave your vehicle. The box fits most SUVs, trucks, cars, and even electric vehicles, making it versatile for different drivers. Since it’s water-resistant but not fully waterproof, heavy rain or deep snow might require extra caution to keep your items dry. While the 14 cubic feet size suits many, those needing lots of space might find it limiting compared to larger options. This makes the Thule Force 3 a reliable, easy-to-use rooftop cargo box that meets the needs of active users looking for moderate extra storage with good security and convenient access.
