I've studied the Dodge and Fords for the last 2 yrs. before buying a new one. I've not read any problems with the 6.7. I test drove the 6.7 w/auto and loved the way it pulled and shifted. If I was buying a truck to have a heavy trailer hooked to like my old Dodge I would have bought another dodge. I wouldn't hesitate to buy a new 6.7.
