The combination of a cargo carrying vehicle and a deck panel. The cargo carrying vehicle has a storage space and a plurality of parallel elongate load beams in the space. A lower surface of the deck panel engages each of the first and second elongate load beams. The body has a plurality of discrete components depending from the lower surface that are abuttable to the load beams to thereby limit shifting of the deck panel. The upper surface has at least a first opening and the lower surface has at least a first complementary projection. A second deck panel, the same as the first deck panel, can be stacked on the first deck panel so that a corresponding at least first projection on the second deck panel extends into the at least first opening to maintain the first and second deck panels in a predetermined stacked relationship.
