These are the best that I have found. When secured properly they don't blow off and with little vibration. I have been using them when towing my RV.

If you are looking for a clip on style, go with ****. They are the best:

I had the ****'s and they look better but they blew off.

Wow. I have run those ***** for 5000 towing miles and they are solid. The wedge holds them on like they are welded.

Had them on my 07, had to tap them off with a rubber hammer.

I had the slip-ons for my 08. Adequate is the only way I'd describe them. Go with REAL towing mirrors. Plus you can likely flog your OEM's through kijiji and recoup a few bucks. Mine are manual telescoping, no memory etc and I love em for towing, heck I love em when I am not towing.
