However, users should be aware of some limitations. Weighing 34 lbs, it should be manageable but might still require some effort to lift and install, especially on taller vehicles. The box's aerodynamics could potentially affect fuel efficiency, as with most roof boxes, although its streamlined shape helps minimize wind resistance. Also, while it's water-resistant, extreme weather conditions might challenge its capacity to keep all contents completely dry.

For those seeking a reliable storage solution with a focus on security and ease of use, the Thule 614 Pulse Cargo Box stands out as a solid choice. However, it's worth considering your vehicle's roof height and your specific weather conditions when making a decision.

The Thule Force 3 XL is a spacious roof cargo box offering 18 cubic feet of storage, making it a great choice for families or active users needing extra room on their SUV, truck, car, or even electric vehicle. Weighing 66 pounds, it’s relatively lightweight for its size, which helps with easier handling during installation. Made from durable plastic, it’s designed to withstand daily use and various weather conditions, although it's water-resistant rather than fully waterproof, so heavy rain might still be a consideration.

One standout feature is its aerodynamic shape, which helps reduce wind noise and drag, potentially improving fuel efficiency compared to bulkier boxes. The mounting system is user-friendly and tool-free, with a clear click indicator to confirm the box is securely attached — this makes setup fast and reassuring. Dual-sided opening is a big convenience plus, allowing access to your gear from either side of the vehicle without having to unload everything.

Security is well thought out with the SlideLock system, which automatically locks the lid and visually confirms when it’s securely closed, giving peace of mind when leaving your belongings unattended. The Thule Force 3 XL is well-suited for anyone looking for a reliable, easy-to-use, and spacious hard-shell roof box with smart security and practical accessibility. It balances durability and convenience effectively, though those frequently driving in very wet climates might want to consider its water resistance level.
