Hi Folks! This is a drawing-board concept for a standing-room two bunk basic sleeper. Under 1000 lb requirement (wet weight), so frameless plywood boat building techniques to be employed. My apologies for the busy layout; there are many overlays; the drawing is not intended for good presentation. It is a clamshell tilting top design, hard sided in up or down position. Very aerodynamic and light, intended for long-distance economic towing behind a tiny Volkswagen golf diesel. 9 sheets of 1/4" ply, 3 sheets of 5/8" ply, stitch and glue construction.
