The factory does produce several types of standard bodies, to which the propulsion units can be attached with only four bolts at each end. (They are always removed for repair.) The smallest and commonest body is a shrunken version of our pick-up truck. It has a tiny cab that seats only two people, and a low, square, open box in back. The rear of the cab can be swung upward to make a roof, and sometimes canvas sides are rigged to close in the box entirely.
