May be crossing over from gas to diesel. Found a 17 with 35k on the clock. All bone stock and is a Certified Ford at the dealer. Anything to be worried about or look out for? I get the additional 12m 12k bumper and 84m 100k power train warranty.

 

All you need to look for are the keys.

 

Despite the '17 being the first year of a new model it has gone quite well, especially for the 6.7L. The 6.2L F-250 had some issues with the transmission that were corrected, and one issue (clunk) that is ongoing with no resolution.

Since you're within the bumper to bumper warranty you can still get a Ford extended warranty if you're so inclined.
