Well, I really liked the mirror that FFT includes in the 2006 Niagara, so I added one.
2006 Niagara Style Mirror (http://www.popupcamping.info/Mirror.htm)
I bought and installed a Vanity Mate in our Yuma. I also didn't like the "fun house" mirror. I removed the brackets holding in the plastic curved mirror and replaced it with an 1/8" real glass mirror. It works quite well now.
