I bought an '08 Jayco Eagle and kept it for a couple years with no issues at all. In fact, it was flawless!! I traded it in on a '10 Forest River (Sierra). At first I thought...what have I done!! It was nowhere near the same quality as the Eagle!! BUT, 10 years of no major issues at all!! As someone said, you always have minor issues to fix.
Now I just bought a 2019 Jayco Pinnacle. It's obvious the quality of the '08 is certainly not there, but so far no issues at all.
As others stated, the dealer is more important.
