I have a question about the CIPA (Lucerix) mirrors that some members are using. I was thinking about putting a set on my Ram, but I had read on a RV forum that some people didn't think that the passenger mirror extended out far enough to see down the right side of the trailer. I'm using the slip-on extensions for the factory mirrors now, and they seem to be OK. I was wondering if someone that has these mirrors could extend them fully and measure to the outside of the mirror(from the window glass) so I would have a dimension to gauge it to in relationship to the slip on mirrors. Thanks in advance,
