This is a 1993 M35A3 Military Truck. I had to list it as a 1980 because of the strange military vin not recognized by ebay. These machines were built for military use and built to last. Caterpillar turbo diesel engine and an automatic Allison transmission the vehicle has more than enough power for every application. 2.5Ton Rockwell military axles for all three axles also indestructible. On board air compressor with service air connection. Central tire inflation system. This truck does have a heater (not all of them do). This truck is also equipped with a hydraulic winch. The hydraulic winches are very user friendly and easy to operate. Older models the M35A2 have PTO driven winches which are much more complicated to operate. I have owned several of these trucks over the years and I prefer the M35A3 over the M35A2 due to the Central Tire Inflation System, large single tires as opposed to the duals, hydraulic winch, Allison automatic transmission with Caterpillar 3116 turbo Diesel.
