A cargo delivery vehicle is described having storage for multiple tiers, or levels, of cargo. The delivery vehicle includes one or more elevator assemblies, each of which includes two cargo storage platforms movable so that cargo can be loaded on both platforms from a height corresponding to the upper storage tier and unloaded from both platforms from a height corresponding to the lower storage tier. The elevator assemblies are provided with stabilizing guide rails along which the cargo platforms are raised and lowered. The guide rails of each elevator assembly are spaced so as to allow loading and unloading of cargo from the front, rear, or either side of the vehicle. To minimize loading of the floor and side walls of the delivery vehicle, the elevator assemblies and their cargo are suspended from a deep center truss extending along the length of the delivery vehicle, permitting the weight of the cargo to be borne directly by the vehicle's axles so that non-structural panels, including cargo access doors and insulating panels, can be used in the side walls and floor of the delivery vehicle.
