Comparing the Single Lens and Double Lens K-Source Towing Mirrors

Question:

Jared, Thank you for your response to my question about towing mirrors for a 2007 Ford Escape. I saw that there is also the K-Source KS3891 that allow to use the mirror either horizontally or vertically. The KS3990 seems fixed in the horizontal position. Which one would give me the most visibility behind a 22-feet trailer?

Between the K-Source Towing Mirror # KS3891 and the K-Source Mirror # KS3990, the # KS3990 will give you a greater range of line of sight.

The # KS3990 dual mirror design will give you a greater expanded view of the road over the single lens mirror of # KS3891. The outer mirror lens will help to lessen the blind spot that occurs when towing a trailer.
