I thought the ford 6.7 engine was made in mexico? seriously pretty hard to buy any brand that doesn't contain foreign parts!
As for the Ram getting bad reviews, I wouldn't believe a word from consumer reports unless I was looking for a new toaster! Yes, if you do decide to go with the ram look into getting the upgraded tranny as was mentioned.
No matter which brand, they all have the way too much pollution stuff on board, but I will add I hadn't had any issues with the new system.
