So I went from a 2012 to a 13. My 12 was the best truck I've had by far but the 3200 mile oil changes and poor fuel economy we're wearing on me. I know the numbers may not be a huge jump but every little bit helps. My main concern is the 13 and up models seem to generate more CEL's. My 12 never did, had it 3 years and never went back to the dealer.
Good news is my 13 has a MaxCare warranty for another 40k miles or till 2021 so if needed that should help.
With my luck the dash will light up like a Christmas tree on the ride home. Hope to pick it up early this week.
