2003 Dodge Ram 3500 4X4 single rear wheel with a short bed. We owned the truck for about 5 years and it has always been our third vehicle. It is a clean truck. The 4wd works fine. It runs good, we have taken it on road trips a lot because it has a lot of room in it for our family. It has air bags on the rear, 5th wheel plates and a turn over ball goose neck. The ac works good and heat is hot. Has new batteries, fan clutch, fuel pump. Oil has been changed, fuel filter changed. Transmission serviced and had new seals put in. Transfer case was serviced and had new seals put in. Front brakes were done recently, the rear rotors pads and 1 caliper was replaced before Christmas. The front end has been replaced recently with MOOG parts. U joints have been replaced over last couple years with MOOG. Has had a new upgraded power steering pump put on. There is no blow by on engine and it does not leak or use any oil. That old Cummins engine just keeps going and going. The truck has 3.73 gears and the best mileage was 21MPG.
