Am I Expecting Too Much?

I know its unlikely I would get any king of refund from Winnebago and I know it seems like a minor problem and if they would warranty in writing the problem would not worsen I would be ok with it. Im afraid in 3,4,5 years this minor problem will become a huge problem. I understand that the wallboard is manufactured with the covering on it, Winnebago buys it in sheets from their supplier and template cuts it, installs it, and then installs fixtures and windows. Its not something that is installed after the coach is built. Like I say, its a minor problem now that is getting worse and I cant imagine how bad the coach would look if the problem gets really bad.
