Abstract
A tractor truck and trailer has a very low profile, elongated body and a cab that is less than half as tall as the trailer. The roof of the trailer extends over the cab but is attached to the truck at its rearward end. The truck may be used with any one of a number of specially designed trailers, depending on the type of freight to be shipped. Dry goods can be shipped with a large, hollow rectangular trailer having loading and unloading doors on its front and/or rear end. Live freight is shipped with a similar, perforated trailer having holes all over its body to provide ventilation to the live freight. In addition, a flat bed trailer can be used for bulky freight. Each of trailer versions extend over the top of the cab of the truck to maximize freight capacity while maintaining an overall low profile.
