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).
