There really aren't any reliability or mechanical issues with that truck. The drive train is well proven and solid. As for the price, you could buy a new one for that amount of money or less. It may not have all the extras this one does but do you really want to pay more for the extras? Maybe you do. I'd price a similar new one first. Unless you have that much cash laying around I assume you will be financing it. You would likely get a better interest rate on a new truck. The payment on a new one may actually be less.
