Abstract: A sleeping facility of greatly improved operational simplicity and esthetically pleasing design for attachment to or incorporation in the side of a pickup truck topper, van, motor home or mobile home, which takes up no internal space in the vehicle, yet provides a comfortable bed protected from the elements which can be quickly and effortlessly deployed for use or stowed for travel in a matter of seconds and requires no power source for operation. The sleeper shell leaves all internal vehicle space unobstructed and obviates the necessity of unloading cargo in order to provide sleeping space. The top 22 and bottom 24, which contains the bed 26, fold into a vertical latched position parallel to each other for travel. Deployment is of extreme simplicity and consists of raising the top 22 with the help of pneumatic spring cylinders 40, dropping the bottom 24 with the bed 26 to the horizontal position and fixing that position with folding supports 38 and 39.
