Review on Enhance Your Ford F150 Towing Experience with Fit System 81850 Snap and Zap Tow Mirror Pair (2015 and Up) by Carl Henderson

Definitely better than standard hitchless mirrors but passenger side needs to be convex not flat. You don't need much of it because it would make things too small, but from the looks of it, you can't see the full length of the 24-inch closed tag (plus tongue). But it's worth it for the driver alone. Instead of looking at the corner of your trailer, you can look down the entire length and look at both the tires and the lane next to you. rear corner or tire.
