I have inherited my dads 1994 F250 7.3 Navistar NO TURBO pickup. Has the automatic overdrive trans and 4:10 gears. He ordered it new. I am flying to go get it and drive it 2000 miles back. I have driven it several times over the years and it pulls good. He and my mom pulled a long heavy tag camper many times through the mountains that weighed 9800 pounds on the scale when it was loaded(the camper was loaded not the driver).
