Hey, Phil, I have come across this thread a few times, and always lost it until now. I have a 2013 Denali 2500 with a Duramax. It has the small power folding, auto dimming, reverse tilt mirrors with the turn signals. I want to upgrade to the power folding tow mirrors for this truck. I thought I had seen a post in this thread with a set of tow mirrors that matched what I already have, and what needs to be done to make them work for my truck. Any help and guidance is appreciated.
