These are aftermarket accessories designed to be mounted on the bed of a specific pickup truck model. They typically consist of a framework of metal bars that elevate cargo above the truck bed, creating additional storage space and mounting points for various equipment. These structures are popular among outdoor enthusiasts, tradespeople, and anyone needing to haul oversized items.
The integration of a sturdy, elevated framework significantly expands the utility of the vehicle. This allows for the secure transport of items such as kayaks, bicycles, rooftop tents, and construction materials. The elevated platform keeps cargo off the truck bed floor, maximizing storage capacity and protecting items from damage. Historically, these have evolved from simple, custom-built solutions to sophisticated, mass-produced systems offering a range of adjustability and compatibility with diverse accessories.
