A vehicle cargo bed has a cargo floor, opposing sidewalls, and a bed lid connected to the cargo bed. The cargo bed is used for transporting objects. The bed lid moves between an open position and a closed position on hinges near a passenger compartment. The floor includes a spare tire cavity. Each sidewall has an interior surface and an exterior surface defining a side of the cargo bed from the passenger compartment to an opposite end of the bed. The sidewalls extend up from the periphery of the floor and each has an upper surface that descends from the passenger compartment and from the opposite end of the cargo bed to form a horizontal surface in between. The bed lid has sidewalls that conform to the bed sidewalls.
