  • Patent number: 6158798
    Abstract: A multi-use structure for use in combination with a pickup truck. The structure includes a pair of longitudinal panels, each panel having a number of pocket stakes that are movably adjustable along the bottom edge of the panel to align with the pockets in the sidewalls of a pickup bed. This adjustment allows the panels to be used as sideboards on a variety of pickup truck models that may have various stake pocket spacings. When the situation requires, the panels may be removed from the stake pockets and the panels may be positioned at the rear of the truck and used as ramps. A strap with a lip positioned at one end of each panel extends down to engage the tailgate or bed of the truck to provide a firmer grip when the panels are positioned as ramps. A pair of sleeves attached at one end of one of the panels acts to telescopically connect the panels in end-to-end relationship where the panels may be used as a ladder or bridge.
