The tow mirrors are definitely a solid upgrade for these trucks. There is a little shake in the glass when driving at highway speeds, and the adjustment motors for the top mirror seem to hit a sticking point, but both of these are very minor issues as I can still adjust the mirror to where I need it and the shaking isn't anywhere near as bad as some other brands.
I do wish the front turn signal was wired to come on with the lights, instead of just acting as an indicator.
Overall a great product though!
