I hope I'm not violating a forum rule here but this forum site:
http://www.r-visioncamping.org
is the place to go for r-vision info. And there is a rally coming up in July in Mackinac City, MI if you're in the area.
We had a 2003 Trail-lite 8263S and aside from one electrical problem, we never had any significant issues. Recently traded it for our Aspect.
