I just traded my Armada, (needed larger tow vehicle) but took off the Tow Mirrors I had and replaced them with the orginal mirrors.
I now have for sale the Tow Mirrors (heated with memory) for sale. Used for 21000 miles, so they aren't new, but clean, intact, and working.
Also posting same in Titan Talk classified forums...
PM me if interested.
Price is $150 plus shipping from Austin TX.
