Abstract: A reconfigurable lower bunk apparatus for a vehicle having a sleeping compartment with a rear wall and first and second side walls is described. In one form, a mattress receiving receptacle or tray is moveably mounted to a rear wall of the vehicle to permit raising and lowering of the tray between raised and lowered positions. A storage compartment is overlaid by the tray when the tray is in the lowered position. The storage compartment may have first and second sections with one of the sections being longer than the other and desirably greater than one-half the width between the side walls of the sleeping compartment. Removable dividers may subdivide the storage compartment into respective storage sections.
