Hi all. Im a newbie in need of some advice. Ive got an 06 silverado with the stock power and heated mirrors. Im going to be towing a trailer and wanted the manual extender mirrors with the power and heat. I checked with my dealer and he gave me an installed price of nearly 1200 dollars. I walked out on him. I found a set on the internet, kool-vue.com, that are oem replacement, power and heated for under 200, that im thinking of getting. They look just like the gm2500 extendables. Any thoughts on these or other suggestions? Second, do i have to remove the door panel or is the connector reachable after removing the mirror? Thanks for the help.
