Stock towing mirrors
The stock flip ups work great. No vibration problems, no adjustment problems and they're always on the truck if needed, not in the garage! They have a large flat area with a small convex section on each mirror, couldn't have designed the reflective surface any better myelf. They do seem to have a bit of a whistle at speed though. I think they're a great option. Not heated, not electric but they stay in adjustment and will never fail. I've never seen a need for heated mirrors, but I do live in California! KISS
