Abstract: A towable vehicle which includes a pivoting access door. The access door is connected to the vehicle frame for pivotal movement between a vertical closed position, and a horizontal, open position wherein the door is supported by the vehicle frame and acts as a step. The vehicle may also include a storage access door which slides outwardly of the vehicle then pivots along an axial arm to provide access to a storage compartment.

Abstract: Retractable extension for a recreational vehicle including two side wall panels, an end panel and a roof panel. Each panel is of solid construction with the wall panels pivoting on a base panel to a horizontal folded position, the end panel has a compound sliding and pivoting connection with the roof panel and both are jointly folded from in-use position to horizontal position. The stacked panels are then telescoped within a recreational vehicle.

Abstract: In a recreational vehicle (10) a pair of pivotally mounted solid wall panels (16,18) which are selectively power (40) actuated by two pairs of operating levers, (16a,18a,16a,18a) between horizontal transit position and upright in-use position, a roof (20) which is raisable and lowerable between transit and in-use positions by compound linkages (144,146) connected one to each of the corners (140) of the roof (20) and at the opposite end (150) to a mid portion of the associated operating lever. There is thus coordinated by a single power actuating means (40) the concurrent hinge movements of the wall panels (16,18) and rectilinear vertical movement of the roof (20).
