My Itasca also has the Velvac mirrors with the little stick on convex mirrors on the bottom corner. When my coach was about 8 months old, I was driving out of the Fl. Keys alone. As I was pulling up to a light at Florida City, I looked to my passenger side mirror and discovered that my little convex mirror wasn't there. It was immediately apparent why they are referred to as a blind spot mirror. :E It was an interesting ride home. A few days after getting home I went out and bought a replacement mirror. Went through the process of properly cleaning the mirror before reinstalling a replacement. The next trip out, I was pulling out of a rest area, with my wife along with me this time, and I asked her to adjust the whole mirror assembly. As she was moving it, the new mirror started to fall off, which she somehow caught. When I got to a campground, I found some double sided tape at the campground store, which I used on the replacement mirror, and it has held up for over a year now. I keep meaning to buy another mirror, which I think I will go out and do now. :B
*** Just bought another mirror for the next time I lose one. ;)
