It's a true Cab and Chassis purchased brand new here in s. Texas. The bed is sturdy J&E manufacturing. I have 3 of those beds. One is over 7 years old and other than the paint chipping, it has held up like it was new. My new crew cab has the same bed but in an 8.5ft because I had to buy a dually pickup and pull the bed off. There were not any cab and chassis available in S. Texas before Christmas.
I need to sell the truck and you can't go wrong with balance of factory warranty and Cummins warranty.
I also have the '89 4x4 Chevy with all newer parts including engine, trans., 4.10 rear, AC, etc. New paint on cab and body. Same 9' bed, but ext. cab. truck. That truck is only $10,500 and it's stout.
