One issue I have vacuum disconnect front axleJay, Have you looked into the 2013s, there really look like they are going to be a big improvement in many ways. More power, better MPG, stronger frames, better front suspension, just to name a few. They will have DEF but that has been around so long that I don't see that as an issue.
U name the issue, think mine was built on a late Friday afternoon just before a long weekend.What problems are you having with it?
