1986 Ford F 700 flat bed, 5 speed stick, yellow, 18' bed 126,000 miles

These vehicles were purchased from a moving company, the boxes were removed and flat beds were put on all of them except 1. We have used them in the field as support vehicles for the harvesting equipment during the harvest season, June through October. They have cosmetic damage, they start and run good but I don't know anything more about the condition other than what I can see.
