A vehicle body includes a pair of side truss members extending in a longitudinal direction of a vehicle, a plurality of cross truss members connecting the pair of side truss members to each other in a width direction of the vehicle, a plurality of cross floor truss members coupled to upper ends of the pair of side truss members, extending in a transverse direction of the side truss members, and spaced apart from each other in an anteroposterior direction, and a plurality of side connection truss members extending in the longitudinal direction of the vehicle and connecting ends of the cross floor truss members to each other.

A vehicle body includes a plurality of shock absorber housings each covering and supporting a respective shock absorber that is configured to be connected to a respective wheel of a vehicle, a pillar member having a first end connected to one of the shock absorber housings to form a corner, wherein the pillar member connects two of the plurality of shock absorber housings to form a portion of a cabin of the vehicle, wherein the two of the plurality of shock absorber housings are disposed at a side of the vehicle at a front portion and a rear portion of the vehicle, and a supporting member disposed at the corner of the shock absorber housing, an upper end of the supporting member being coupled to the pillar member and a lower end of the supporting member being coupled to the shock absorber housing.

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.
