5th Wheel Truck Tool Box

Maximum storage for life on the go.

Highway Products invented the 5th Wheel Truck Tool Box because customers wanted a box that they could place against the truck cab and still be able to open it. The back of the box is notched so the back of the lid has a place to go as you open it. This space-saving, flush-mount truck tool box secures to the bed of your truck and sits flush with the side rails. The low-profile design increases visibility and allows your 5th wheel to swing freely, without hitting the lid during sharp turns. Constructed from .100 military-grade aluminum, this corrosion-free box keeps your tools and gear secure and dry. The 5th Wheel Truck Tool Box is available in sizes to fit all pickup trucks and comes with our lifetime warranty.
