The application of all-wheel drive vehicles to the desert environment is not new or unique, but model changes occur that incorporate improvements of components or manufacturing techniques. This paper deals with one specific six-by-six power-shift model that was first marketed in 1973. (“Six-by-six” refers to a six-wheel vehicle with all six wheels capable of transmitting power from the engine.) A description of major components and how they are matched may be a useful tool for future designs. The cooling system and tires are the major differences in the desert six by six, when compared to the conventional all-wheel drive units applied to the United States construction market. These are discussed in detail.
