Abstract: A modular RV furniture apparatus includes a platform, a U-shaped frame having enlargements formed at its leg extremities for insertion through selected socket openings of the platform. A key panel movable under the platform has key openings formed therein for locking the frame in place with the enlargements blocked by the key openings. The leg extremities of the frame are spaced at a distance D, pairs of the socket openings also being spaced at the distance D for permitting the frame to be selectively engaged with the platform and locked in place in a plurality of fixed positions. At least some socket openings are spaced at a center spacing S that is a submultiple of the distance D, a back-support on the frame having a width W being the distance D plus a multiple of the spacing S. A manual or powered locking device holds the key panel in the locked position, an electrical interlock deactivating a vehicle ignition circuit when the key panel is not in the locked position.

Abstract: An improved motorhome in which the features normally requiring a large driving and housing space are achieved in a compact area by utilizing a pair of transversely positionable trundles each carrying a fixed cushion portion and a longitudinally movable, track-carried cushion member each such cushion member comprising a pair of cushions selectively rotatably about a common axis from a horizontal position, when a bed function is being performed, to a vertical or semi-vertical position, when a driver's or passenger's seat function, or a lounging function, is being performed, servo-mechanical means being provided to move and lock each cushion member in the appropriate longitudinal position and the rotatable cushions in the desired elevational position.
