2004 Ford F650 Rollback 21ft Jerr Dan, I owned the truck for 3 years, I was the only driver, truck had oil changes every 5,000 miles and every 10,000 for the fuel filter. The truck runs and drives as it should even with heavy loads. Both fuel tanks were new when I bought it, also replaced complete exhaust. Two years ago I replaced all wheel bearings and races, front and rear. A year ago I had the bed removed and had 16ft of the cross members and decking replaced to OEM spec. At that time, I had bed slides replaced with track assembly. Had complete overhaul on the wheel lift assembly, all bushings and pins were replaced. All the control hoods and levers were replaced. Beginning of this year replaced all 4 u joints that are serviceable. Replaced both sending units for the fuel tank, transfer pump and feed pump and 6 new Bosch injectors (the warranty is good until 02/09/2016) 95% of the parts are OEM parts. Rear tires are 16/32 and front tires are 8/9/32 , all the breaks are around 11/32. If you have any questions or would like to see the vehicle, please contact me, My name is Chad 717-773-6038.
