My first test drive of my 1962 GM PD4106 Bus. This bus originally was a Greyhound Bus PD41061346. Central Greyhound Lines Kansas City Missouri, put into service 4/7/62. The bus has an 8V71 Detroit Diesel engine, with an Allison V730D Automatic Transmission. It has been retrofitted as an RV, with front lounge, and kitchen and dining area, bunk beds, a bathroom, and a rear bedroom.
