I have a 2013 gmc z71 cc duramax, i have a gulf stream aztec i have the rock tamers to protect the front of the trailer i am wondering how it will work with the diesel when the truck goes into regen ...
There are a few random (and rare) reports of melted fronts on 5ers, I have never seen one on a TT. I have seen MANY melted mudflaps on dpf equipped trucks around here. If it touches the exhaust, or is inline it to a few inches behind the tip - you are likely to have discoloration at minimum, if not disfigurement.
