I found a 48 1 ton duelly with a grain bed and lift. It's in Northern Kansas. I bought my new 49 3600 in Okla. I'm not trying to sell this truck, but it looks very straight and is supposed to run. The guy also has a 49 3600 with some kind of chain drive feed bed on it. If any one is inrerested send me a private e-mail and I'll forward the info to you. I hope this is ok, just trying to preserve a nice old truck.
