What is a reasonable maintenance wait time

I don't mean to toss salt into a wound, but when I was shopping for my A, the Palazzo was off my list. And I was bummed about that. I really liked several of the floor plans and the overall comfort of the rig. But after researching and learning about similar issues, such as you are having, I went another direction.

Someone mentioned the "A" word. It might be worth an hour consultation with someone sharp on warranty issues to review your options.

Good luck getting this resolved to your satisfaction.
