I've got factory tow mirrors on mine, and I might be in the minority here, but I really don't like them. I find that when I pass a car on my right, I can clearly see in the rearview mirror I'm past them, but the right side mirror looks like they are still right next to me. People say to use the small blindspot mirror, but it is too small and makes things look too far away. I found when pulling the trailer, I could adjust them to see the trailer or the traffic, but not both. Again, I can see both in the small blindspot mirror but it is too small. I've tried turning them, but that didn't help much for me.
Based on this experience compared to the mirrors on my old Tahoe, I think I'd be happier with regular "objects in mirror are closer than they appear" mirrors. Just my $. 02.
