Abstract: A truck bed member includes a rectangular top side with a long side along a first axis. An interlocking side is fixed perpendicular to the top side along a first edge of the top side parallel to the first axis and includes an interlocking member along an edge opposite the interlocking side coupled to the top side. An interlock receiving side is fixed perpendicular to the top side along a top side second edge opposite the first edge and parallel to the first axis. The interlocking side and the interlock receiving side are parallel to one another and extend a same direction from the top side. The interlock receiving side includes an interlock receiving member along an edge of the interlock receiving side opposite the edge coupled to the top side. The interlocking member is configured to couple to the interlock receiving member of a different truck bed member.
