1974 Marmon. We are the second owners. Bought the truck from the son who told us that his father toured the plant while the truck was built. The truck has air slide 5th wheel, Dual exhaust, A.C., 350 Cummins [which is apart] 13 spd, Power R.H. window, and FACTORY air ride susp. A lot of truck for 1974. I have a donor engine from a convential for it.
