One thing you ALSO want to consider in your decision is the cost of ownership....how much are the parts to repair it when needed going to cost and if your going to have quick access to those parts when needed.
Also if your going to rely on the dealer for the repairs what is the labor rate going to be and how reliable is the dealer,are they going to be there soon or "when they get to it"?
some dealerships will practically give a truck away just to get your business then make it up in parts and labor later on down the road.
Also another thing is how easy is the truck to repair if your doing the repairs yourself,are you going to be even able to do the repairs yourself or is it going to be that your going to need the dealer to work on it because they have the proprietary laptop and cables or other diagnostic equipment not availabke to the common man
