My 2012 Ram 3500 gets 21mpg on the hiway. couldn't be happier.Why not look at Ram? In particular, the 2013 and 2014 give excellent mileage with the new emissions strategy (DEF), and the Cummins engine has been reliable since Dodge first used it in the 1989 models. The 2007.5 through 2012s, however, don't give such good mpg figures. Ford keeps coming out with new "improved" engines and then has to drop them after devastating warranty problems.
As a dealer, I go to many auctions and see all kinds of vehicles with all kinds of miles on them and this ^^^ statement can't be more true.I've never seen one hit 200k without a major failure. Most have multiple major failures. If it was all they hoped it would be they wouldn't have designed the 6.7 themselves. Being able to load a 300hp tune on a stock truck is pretty cool. That is also part of the problem.
