Lemon laws can vary from state to state. In UT and I suspect most states, lemon laws apply to motorized vehicles and not RVs. As for service issues, I found out that many RV repair services are "authorized" to do warranty repairs. It may be worthwhile to make some phone calls to other local service shops or even mobile service operators. They get things done a lot quicker than dealers seem to be able to.
I agree with Jim that if you're going back to the dealer, it is wise to get the GM involved. I'd set up an appointment with the GM and the Service Manager. Let them know how disappointed you are and what your expectations are. Polite calm but firm seems to work best in my experience. We thought we had a "lemon" with our Cougar, but the GM and service folks at Camping World got everything fixed. After 4 seasons we're down now to the usual wear and tear items and enjoying our RV investment.
