A storage system ( 14 ) of a motor vehicle ( 10 ) presenting a cargo space defining an opening ( 18 ) for storing spare tires, tools, and the like. A load floor assembly ( 22 ) is configured to cover the opening ( 18 ) and to support various loads ( 41 ) positioned thereon. A cover ( 24 ) of the load floor assembly ( 22 ) is molded from a polystyrene or other foam composite. At least one laminate ( 18 ), formed from a hard board or other sheet material, is adhered to the cover ( 24 ). A support frame ( 40 ), formed from a foamed polypropylene, includes a density greater than the density of the cover ( 24 ) and therefore has a higher mass to provide a significant amount of structural benefits to the load floor assembly ( 22 ) for supporting and preventing a deflection of the cover ( 24 ) under the force of the loads ( 41 ) applied thereto.
