Abstract

A recreational vehicle includes a lower body and a vertically telescoping upper body. The upper body includes a second floor, fully suspended when the upper body is raised, and resting on stops when the upper body is lowered. A lift mechanism includes a take up drum, lift line, and pulley system to raise and lower the upper body including the upper portion of the telescopic elevator shaft while telescoping corner posts support and guide its motion. A elevator has bottom and top floors connected by vertical columns and a lift cable extending from the base of each column through top and bottom pulleys of an adjacent corner post to a power take up drum to raise and lower the elevator. A vertically movable bathroom is similarly provided.
