That would be, November 10, 2017. That is probably the last 2017 built. No different than a early '18, considering no significant changes, correct?

 

Mine was built Oct/Nov 2016 ('17 F-250 6.7) The only issue I had in 52k miles was the transmission that had to be rebuilt due to some defective fittings or something. The DTE thing is annoying but I never got it fixed. Other than that its been flawless. I'd say go for it.

 

I think you will be fine with either one. With that said, my 17 was built first week of September and it was delivered last week of the month. Happy to say -- no issues what so ever.
