If I were buying a new Ford, I'd want to wait at least until the end of the 2017 model year or better yet, get a 2018. Lots of gadgets and gimmicks on that new Ford which I'd prefer to see all the bugs are worked out.
I'm still a big fan of this generation Ford right now (2011-2016). I've had three, I work them like dogs, and they've been great. I've never heard of a frame problem yet.
Would love to see the new 2017 specs as well. Surprising they're not widely known. Not surprised the salespeople don't know.
