Hi, I can't find the value for a truck this old...so can any of you give me some assistance? What it is is a 77 Ford 1 ton , 2wd, hydro dump bed, 3 speed w/ bulldog (?), new tires & wheels, believes 109,000 miles (it says 9,000 on the odometer), everything is pretty much in working condition, needing rear breaks soon. He's wanting 3900 for it. I'm guessing this is steep? What do you guys think?
