If it’s a one owner truck, how old is this fellow? I don’t buy that for one second. I’d want to pull some pieces off the engine to see if it has been rebuilt. Pull some plugs, the valve cover, and the lifter cover. That could tell you a lot. I’d call him out on it and want to see all the proof he has. It is a very solid truck, but grill the guy good to make sure you’re happy with your decision. If it seems to good to be true... it probably is.
