I ran HD mirrors for about 6 months with no problems. I was able to get the passenger mirrors in a position where I can see them past the dash hump. I just recently switched to RR relocation for the ease of pulling the doors off and hitting the road without having to mount the mirrors in the hinges and position them perfectly every time. That routine gets old quickly. I quickly got used to loosing half my passenger mirror with RR brackets so it doesnt bother me at all
