Most Popular Longview for 2012 GMC Terrain

They were delivered expeditiously, went right on as per the instructions and they are fully adjustable so I can now see both sides of the trailer when straight. It is a 8.5 foot wide enclosed car trailer. All good here.

These mirrors helped tremendously when towing my Micro Minnie travel trailer versus stock mirrors on my GMC SIERRA 1500. The extended mirrors enabled to better determine when it was safe to move back into my lane after passing a vehicle and allowed me to see better the vehicles behind trailer. Although there was an occasional slight vibration in the passenger side mirror, it did not disrupt the usability of the mirrors. The towing mirrors took only a minute or two to install and fit perfectly on the stock mirrors. Adjusting them properly takes a little more time and is easier when a second person helps. I am extremely pleased with this purchase!
