Underbody vs Wheel Well Storage
Material and Build
The VEVOR 30" Underbody Aluminum Truck Box uses heavy-duty aluminum alloy with a diamond plate tread pattern. This material resists rust and corrosion better than iron, and the thickened panels protect against scratches during long drives. In contrast, the VEVOR 6.6 Gal Wheel Well Box is built from impact-resistant ABS plastic with steel mounting brackets. ABS offers durability without the risk of metal fatigue, while the steel brackets provide stable support. Aluminum generally offers superior strength-to-weight ratio for structural integrity, whereas ABS provides excellent impact resistance against road debris. Both designs prioritize longevity, but they achieve it through different material science approaches suited to their specific mounting locations.
Storage Capacity
Capacity differs significantly between these two units. The underbody box measures 30 x 17 x 18 inches, providing a large, rigid interior volume suitable for bulky items like camping gear or large tool sets. Its dimensions allow you to store substantial equipment securely underneath the vehicle. The wheel well box offers 6.6 gallons (25 liters) of space. While this is less volumetric capacity than the underbody unit, it is optimized for the wheel well cavity. It includes a movable tray for organizing smaller items like clothing or drinks. If you need to haul large, irregular objects, the underbox wins. For organized, smaller gear, the wheel well box is sufficient.
Compatibility
Compatibility is a major differentiator. The VEVOR 6.6 Gal Wheel Well Box is designed for specific truck models, including 2002-2018 Dodge Ram 1500, 2500, and 3500, as well as other variations for Chevy/GMC and Ford F-150. It requires drilling and precise fitment to the passenger side wheel well. The VEVOR 30" Underbody Aluminum Truck Box is universal. It can be installed on trucks, trailers, campers, or pickup racks, provided you have the underbody space. It does not rely on vehicle-specific mounting holes. If you have a specific truck listed for the wheel well box, it offers a tailored fit. For any vehicle or trailer, the underbody box is the only viable option.
Weight and Profile
Weight affects your truck's payload and handling. The aluminum underbody box weighs 25.1 pounds. Its dimensions (30x17x18 inches) create a substantial profile that sits low to the ground. You must ensure your vehicle has adequate clearance to avoid scraping. The wheel well box is lighter at 15 pounds. Its dimensions are 31.5 x 8.78 x 15.1 inches. It fits snugly into the wheel well, utilizing existing space rather than adding bulk to the undercarriage. The lighter weight of the wheel well box reduces overall payload impact. However, the underbody box’s aluminum construction distributes weight differently. If minimizing added weight is critical, the wheel well box is the better choice.
Security Features
Both boxes include locking mechanisms to protect your belongings. The underbody box features a latch lock and comes with two exclusive keys. It also has an embedded T-shaped handle that sits flush to prevent scratches. The wheel well box offers double lock security, including an anti-theft key lock and an anti-pry combination lock. The combination lock adds a layer of security without needing a key, which can be convenient. The underbody box relies on a single key system. The wheel well box’s dual locking system provides enhanced protection against prying. If you prioritize multiple security methods, the wheel well box has the edge. Both keep items dry and secure.
Access and Usability
How you access your gear matters for daily use. The underbody box requires you to open it from underneath the truck. You need to reach under the vehicle to use the T-shaped handle. This can be awkward if you are in a tight space or need quick access. The wheel well box features an 180-degree rotating design. It swings out effortlessly, keeping items within easy reach without climbing into the truck bed. This design allows you to access contents while standing beside the truck. For frequent access to tools or items, the rotating wheel well box is far more practical. The underbody box is better for long-term storage where frequent access is not needed.
