Glad to hear you're getting some movement. That's the very reason I only make my coach purchases in the late fall, I can get in a few checkout runs in the off season and have all winter to pester the dealer to get parts in if needed, and to replace them. My coaches will never sit for weeks on end at a dealer, I get confirmation of parts are on-site (All parts) and then they have a day to fix it when I bring it to them.
These things cost too much money to just sit on a dealer lot post-purchase IMO.
