I had a few things I wanted taken care of when I bought my Journey. Dealer took care of some, but I wanted to travel. Months later I went to the factory in Forest City. They were most willing and helping solve my concerns.
Then just this last May, I went back to complain of the clear coat peeling off the front cap and the side radius. They sent me down to CDI the paint contractor. Per private estimates, they did over $2000 worth of paint and clear coat for free.
If your dealer can/will not make you happy, I would contact Winnebago and see what they say.
