Then I tried these http://www.amazon.com/Fit-System-389...4584293&sr=8-1
They don't look as nice but they go on easy and are much easier to adjust. They also have a much bigger mirror which results in a better viewing area.
Now that I have my Ram (also a sport) I still need to use an extended mirror but haven't put them on this truck yet. I've towed the camper twice with it and I really should put them on but hate to deal with any clip-on. And I don't like the looks of the stock tow mirrors. If I towed the camper enough I would go with them but I don't so I'll deal with the clip-on's.
Bottom line I'm not sure there is such a thing as a good clip-on mirror. But some might be better than others. Good luck finding one that will work for you.[/QUOTE]
Went with same ones on your recommendation and they work great with no vibration, got mine on amazon.
