Every single truck ever made has some sort of inherent problem, some worse than others. You can go to any big 3 truck forum and cherry pick particular common problems and repost them. Sure the 6.7 Ford has some turbo failures, what percent? I'm a hard #'s guy. I mean you really can't get that # by coping and pasting posts from a forum from people WITH PROBLEMS. Or from one or 2 guys that had a problem, not a good way to get a solid #. Hell, how many people post threads on there that everything is A ok? Not many. I know a couple of guys with 6.7's with zero problems, not a good sample size to say they are bullet proof, just 2 dudes out of 10's of thousands trucks.
I really don't have a dog in this fight besides owning an old Ford (I actually post what I own in my signature). I'm not a Ford only guy either, hell, if I was gonna go blow $50k, I would consider A new Dodge or a Ford. It just seems some people have a negative agenda whether they don't like Ford or Diesels in general.
