Those mirrors are pretty bad azz. Did they come with a captains control for the Passenger side?
While you already have them and the wiring laid out on the mirrors have you considered adding heat? It is not a huge deal unless you head out to West Virginia or other mountainous areas where you can get freezing rain pretty easily.
They will really shine when your driving up a mountain and are able to hit defrost instead of having to stop every 15 minutes to scrape off the ice. I know I am all spoiled and junk but I don't plan on towing without heated mirrors after having and not having them after a fuse blew.
For all I know you may not put yourself in that situation though.
