Responsible Use in the Newmar Canyon Star manual?

The manufacturer has to follow the rules. RVIA says it's temporary housing then that's what it is.
We use our coach 6 months in the winter in FL and 3 months in Northern MI. The other 3 months we generally spend at our S&B. If Newmar, the RVIA or anyone for that matter looked in our coach you would think that we don't use it all. This is our 8th year of ownership and it has been a GREAT coach for us. Regarding your concerns, I don't think I would worry about it. Use it and enjoy it. JMHO!
