The invention consists of a panel having an area that is substantially the same dimension as the tail gate on a pickup truck cargo body. The panel is suspended from a track mounted on the body side rails, and through a wheel assembly rides the length of the truck bed. Cut out areas allow the panel to move past the wheel wells and doors attached to the panel are adapted to close off the cut out areas when not obstructed by the wheel wells. Locking bolts on each side engage slots in the side rails and slots in a floor mounted track. A single handle on each side controls the movement of the vertical and horizontal locking bolts.
