If your at all hesitant about the engine, then why not look for another truck! There are plenty of them out there right now, most that are priced better than that. I've heard too many horror stories of those 6.0s from people I know, let alone all the stuff online about them, to ever consider buying one! Whats the point of getting a good deal if you have to turn around and sink $5000 into it once you get it home! I would seriously be looking at other trucks/engines if I was you.
