Military vehicle trailers for general cargo are designed to be used with a specific truck or range of trucks so that the towed weight matches the capacity of the prime mover. Wheels and tires are often the same on the truck and the trailer, providing more capability to recover from a flat tire or damaged wheel. Trailers with a lunette match the height of the truck's pintle within a reasonable range. The intervehicular cable from the trailer matches the socket on the truck.
