1983 Steinwinter Supercargo 2040 Cab is probably the strangest truck ever made

7. On the plus side, the trailer opens on both ends

allowing a straight in approach to loading docks, more versatile distribution of loads, and more flexibility in making numerous stops. On the negative side is the absence of landing gear - the legs that hold up the trailer when detached from the truck, the safety risk created by the diminished range of vision for the driver, and no sleeping quarters.
This truck would be well suited for local delivery but the lack of landing gear makes each truck less available for additional trips while loading. Also, while the range of vision could have been a problem in 1983, with the in-cab video available on today's vehicles that problem is lessened.
