Good point on the spare. With all the thought placed into to this motor what are they thinking with a undersized spare? Please tell me they left enough room for a full sized spare in the carrier. This is Fords third different design in 7 years. Whether they have done extensive testing or not, doing it in a controlled atmosphere is nothing like the real world. Put 20K behind the truck and tow it for 200K and then see whats happening. I for one would be leery of buying a first year model in any design.

That being said I don't think you can go terribly wrong with any diesel built today. They all have certain issues and always will.

good luck
