Abstract: A tailgate for enclosing a pickup truck bed includes a sheet metal wall having upper and lower edges and opposite sides, and a stair with at least two steps integrally formed in the wall and extending between the opposite sides. Side walls are mounted on the opposite sides of the sheet metal wall. The lower edge of the tailgate includes a mount for mounting the tailgate to the pickup truck bed for pivotal motion between open and closed positions. A latch on the wall releasably secures the tailgate to the truck bed in the closed position. Flexible cables hold the tailgate in the open position with the steps horizontally orientated.
