Truck has lot of work done to make it last. For example; blue spring kit, egr and oil cooler up grade, new steering and suspension, plus lots more. I do have paper work for everything done to it.I bought the truck with the intention on keeping it for the rest of my life. The only reason I'm selling the truck is to help pay for my dogs cancer surgery.It will be a great truck for anyone who gets it.Truck has lot of work done to make it last.
