H-series cargo box on D-series chassis. Inspired by the Mule from GTA games (3D universe). Uses a heavy duty crew cab frame + regular cab. This mod also makes regular cab available for crew cab frames, not sure if you need it. Comes with three configurations. Press "O" to open doors. Doors may be not operable if you have other D-series mods with custom bindings enabled.
