Abstract: A camper vehicle wherein substantially the entire roof and interior ceiling panel are both pivotable each about opposite longer sides of the vehicle's body. The roof pivots an arcuate movement of about 75.degree. and the ceiling panel of about 180.degree.. Articulated struts pivotably connected on one end to the roof and on the other proximate the hinge for the ceiling panel secure the roof in its open position, the struts being locked in their extended positions by a slideable member. Although straps from the upper longer side of the roof to the opened ceiling panel support the ceiling panel in its open position, outside poles may be utilized to assist in providing such support.
