Review on Towing Mirrors Compatible Heated Extendable by Kyle Tebow

Installed these mirrors on my 2016 Big Horn, the original truck mirrors all had the same features so it all connected. When starting my truck, my DEF system error message and check engine light came on. Was am. The next day it was gone and everything was fine but the ambient temp on my truck wasn't nearly the same. The truck then continued to receive DEF error messages. Mirror removed and reinstalled, all problems gone. The passenger mirror is also greatly enlarged and thus practically unusable. My biggest regret in all of this is that I left them in the box for a month before installing them and now I'm stuck with them because time has run out to return them.
