I've been asked this several times, mostly by the dealers.
I had the clip on CIPA panoramic view to attach to the mirrors of my truck, then the fender mounted mirrors that were removeable, and finally on my GMC I went to OEM Factory Towing Mirrors for this setup.
Matt, I use Custom Towing Mirror of Rochester, Michigan…..Tel. 248-844-1400, which provides towing vision without obstructing existing mirror. Custom Towing offer at least 18 different configurations to fit several applications. I use model 2200A, used on Ford Ranger and Explorer…… late 1995-1997. Unit friction-fits (grips) with one screw-adjustable retainer clip. I can see front to rear both sides of our 14RK, with very little vibration (distorsion), while sitting/driving the Explorer.
