Hi All, I've got a 96 f350 7.3 powerstroke mason dump with 41,000 miles! Yes, it's true. Good shape, usual rust underneath. New rear leaf springs, tires, ball and axle joints. Oil pan is fine and original. Drives and runs great. Just this and that over the years and I'm ready to get something newer. What could I expect to get for it? I'm thinking list it 20k and take 18k. Crazy?
