Abstract: The present invention provides an improved housing shell that can be bifurcated into a base mounting member and an upper removable roof member. The shell is configured for mounting on a truck to enclose the truck bed. The truck bed can be modified to provide extra seating capacity with the rear of the cab removed and an aperture cut in the truck bed to receive an auxiliary floor member. Special bucket seats can be mounted over the rear wheel wells, or apertures can be cut in the rear wheel wells for mounting for bucket seats.
