I think he drove a dodge
found it
Uncle Jesse's truck varied.. in the first few episods it was a late 60s to early 70s Ford Stepside.. inteh first reunion it was the same era, but a fleetside(flat).. most of the series it was a 73 to about 78 Ford Truck, again it varied between F100 to F250, short bed and long bed were both used. But if you get a white 1973-75 Ford F100, you will be pretty right.
but realy I would not sell that truck i would keep it in the family buy it from him if u can . the price of that truck is only gona go up $$
