Sounds like you need to step up and be a bit more aggressive with the dealer and the factory. If a dealer laughed in my face about legitimate complaints, after restraining myself from slapping the taste of his mouth, I would be on the phone with the factory and or my lawyer. Absolutely unacceptable. But if you don't fight for what's right, your stuck. Don't sit back and allow them to screw you over
Edit: Just saw that they were addressing your issues. Best of luck. And make sure to report that dealer to the manufacturer. It is dealers like yours that are helping the RV industry SUCK more than it needs to
