Mine is a 2003 and the only real issues I'm dealing with are from the rig sitting too long in one place so I can't blame anyone for that.
I have contacted Jayco by web form and email on a few issues I'm working on though, and my experience is that I get a fast and polite reply promising to have someone help me with my questions, then, nothing. Maybe someday my ship will dock and I'll be able to buy a new unit to see if they will talk to me
