Several of us have them. Aside from the link posted, try the "Search Forums" tab, punch in Clear View Mirrors, and several posts should come up.
I have them and after using them, wouldn't tow without them.
It might be feasible to spend a bit extra in cash this spring, and I just remembered clamp on tow mirrors sucked last year. I lost / broke 3 out 4 purchased. (cheap ones yes)
so those who installed clear view tow mirrors which is your favorite. the next gen dual mirrors, or the compact single mirrors? with $20 difference it isn't a matter of price, but which ones work better for the Ranger with an 8' trailer? do the double mirrors help in that regard?
I have the dual...compact weren't available when I got mine. But, would have still got the dual as the bottom convex comes in handy when backing, especially with a trailer. Also great when towing ...lets you see in blind spots.
And, I'm towing a full size, 8 foot wide travel trailer.
