Becoming a line up of motorhomes, the Diplomat name was first used in the early 1970s under Executive Industries. Executive and the Diplomat name were eventually acquired by Monaco Coach Corporation. Having built Class C motorhomes, Diplomat spent the 1980s building larger Class A motorhomes ranging from 24 to 40 feet in length. The Diplomat name was discontinued after the 1988 model year replaced by the Executive moniker.
