1956 Ford F-500 Dump Truck. The 1956 F-500 was the first year that Ford came out with the 12 volt system and first year for the curved windshield. 1953 to 1955 look similar but the cab was different and the windshield was flat glass. Therefore, this 1956 Ford F-500 is a rarety. All lights work properly, high beam indicator, directional light flashes, and the dash lights work. Heater is nice and warm. Forest Green matches the current owner, since he runs a local tree trimming company. This powerful truck drives beautifully and shifts very nice. More photos to come. Well maintained and Garage kept in Massachusetts.
