Truck Information:
It was made in 1954, but this Diamond T 951S would look good on the road today. The Diamond T brand has often been referred to as the Cadillac of trucks and was responsible for many advances in truck design. These include the fin and tube radiator, the adoption of 7-bearing 6-cylinder truck engines, 4-wheel hydraulic brakes, fully enclosed deluxe cabs, and hydraulic shock absorbers as standard equipment for heavy duty trucks. Even after its purchase by White Motor Corporation in 1958, Diamond T continued as a leader in truck design. This particular Diamond T began its service in Phoenix, Arizona pulling dump trailers. In the early 1980s, a collector purchased the truck and began an extensive restoration and modification that included swapping out the engine, upgrading the transmission, and adding a sleeper cab. This truck was purchased by Richard Guerrera in 1990 and further modification was done. The Guerrera family has graciously loaned this truck to the Iowa 80 Trucking Museum to display. Top Speed: 65 MPH
