Military trailers designated as a chassis are manufactured as a base. Other equipment or components will be added to the chassis, often resulting in a new item with a differnt model number.

The chassis trailers were used as a base for the development of specialized equipment like power units, laundry equipment, field kitchens, welding sets, decomtamination equipment and much more. The chassis trailer in a given family of trailers was also usually the base for the common cargo trailer, with the addition of the cargo box to the chassis. For example, the M103 Trailer, Chassis with a cargo box added becomes the M105 Trailer, Cargo (1 1/2 ton 2-Wheel).
