Manufactured in 1962 by the Roustabout Company in Frackville, Pennsylvania (USA) the Trivan was a 3-wheeled lorry with a fully enclosed cab for two people.  With seven years of testing, the vehicle was designed by C. Harry Payne, who was also became known as The father of the Jeep*, the originator of the military Jeep in 1939 that was used so heavily during World War II.

The Trivan’s power came from either a Kohler 32hp 2 cylinder 4 cycle air cooled petrol engine or a 30hp 2 cylinder 2 cycle air cooled diesel engine that powered the single rear wheel.   Both engines gave the vehicle a maximum speed of around 55 mph.  The Trivan had a fiberglass body attached to a heavy duty steel tube chassis and airbag suspension.   All models had an open pick up type rear body with drop down sides.  A fully enclosed rear body was designed for a prototype but never manufactured.

Production ceased in 1964 after 112 vehicles had been made.  A number of them were purchased by East Coast Trailways affiliates.
