2006 duramax diesel 2wd. Crew cad. With 12' grain dump with side door. It has 31500 miles on it. Was trying to figure out what I should try to sell this truck for. Really solid truck has a 17000lbs gross weight. Has a side tool box as well. I've maintained very well rust is very minimal. Never seem the road in the winter so salt has never been a issue.. Also included would be the mesh tarp and hoops for a leaf loader setup. Based on comp trucks I've seen I think I should ask high 30's for it.. any thoughts?
