I'm a Jayco owner who believes that Jayco quality is neither as good as it ought to be, nor as good as it could be. And neither are very many of "entry level" RV's, and even expensive ones.
Problems I have NOT had with Jayco are basic structural problems - things like frame welds breaking, axle mountings breaking, frames bending. Which do happen, but I like to think not so much with Jayco.
Jayco does have a good warranty, but how good the service is and how quickly a problem is solved depends on your dealer. Investigate, investigate, investigate.
I'd buy another Jayco, and I can also say I'd buy it from the same dealer.
There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.
