A motor vehicle for carrying a load over a street has in a preferred embodiment a bottom platform for supporting the load, a frame, disposed above the bottom platform and mounted to it, for providing structural integrity to the vehicle, a plurality of wheels rotatably mounted to the frame, and a door arrangement disposed on a side of the vehicle. In further embodiments, the wheels are retractable, so as to permit the bottom platform to approach the street level to facilitate loading and unloading of the vehicle. Additionally, the door arrangement includes a large doorway and a plurality of doors, each door slidably mounted, and all doors are movable to an open position located near an end of the vehicle to expose the large doorway to facilitate loading and unloading of the vehicle. A ramp is hingedly attached to bottom platform, so that the ramp may be folded into an up position and unfolded into a down position, and in the down position it may provide a smooth transition from the bottom platform to street level.
