After World War II, new trucks were planned. Many trucks had worked well, but there were too many types. Companies built their own types. The Army wanted types that anybody could build. They also wanted fewer types. There would be and -ton 4x4s and 2½, 5, and 10-ton 6x6s. These trucks used many of the same parts. All large trucks used the same cab. The fenders and hoods looked the same.
