mudfuel07 - Before you go dropping a few hundred bucks on a 08+ towing mirror kit, check out the C-Betr Mirror set for the Super duty. I have them installed on my truck and they are just as useful as the later model convex mirrors. I have them set so that I can extend and retract my mirrors and they still worked fine for the 5th wheel after some minor adjustments. I been considering moving them to extended position but then ill have to get into a habit of folding my mirrors in some of the parking lots I deal with.
C-Betr Mirror SetAt 45 bucks, it was the only option before the 2008 set was out there and now still pretty economical.
