For around $10k more you can get you a brand new one with no miles, under warranty, cheaper insurance, and a lower interest rate, then do what you want to it and know it's done right. You don't know how well this truck was taken care of, or when the mods went on and how long before something breaks. Me personally, I'd go new if you could. Gotta realize, that truck is already 5, almost 6 years old. As soon as the 19's drop, price gonna go way down.
