Abstract: A recreational vehicle comprising a chassis having a cab and a back wall attached thereto. An opposed pair of side walls are at least partially defined by a portion of the cab. Moveably attached to the chassis is a pair of slide outs which each extend from the cab to the back wall. Each of the slide outs defines an outer wall, and is selectively moveable between an extended position and a retracted position. When the slide outs are in the retracted position, the outer walls thereof are substantially flush with respective ones of the first and second side walls. When the slide outs are in the extended position, the outer walls thereof protrude outwardly from respective ones of the first and second side walls.
