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 ...
I saw one recently that included a stainless heat shield attached to the right flap. Hearing some have had problems with discoloration on the front of their trailer, I'd spend a couple dollars for the metal.
