GMC sold the RTS design and patent rights to Transportation Manufacturing Corporation (TMC) of Roswell, New Mexico, in May 1987 though the two companies did a joint order for the New York City Transit Authority to prepare TMC for the production. TMC would sell the design and patents to NovaBus in September 1994 in the midst of an order for the Massachusetts Bay Transportation Authority. Production under NovaBus would continue until 2002 when NovaBus left the U.S. market.
