Maybe it would have been more civil if the OP asked that only those that have direct experience with a 2013 6.7 respond rather than those who have never owned one but can use Google. Or those that have a friend of a neighbour's 3rd cousin had heard that they had trouble with their 6.7.
For those Ram owners, don't forget your Rams have a Ford blood line. I'm sure you're aware that the Dodge brothers worked for Ford before going out on their own. :E
