mountaineer montana travel trailer/ service

I purchased a 2006 montana mountaineer travel trailer last 10 months ago. When we stored it for the winter/slide was in. It leaked and received quite abit of water damaged. The dealer I purchased it from said Keystone only will clean the carpets to get rid of the mold/ that is not taking it up and replacing the pad or seeing what the floor looks like under neath. It also ruined my entertainment center and the wood trim around my slide. They did say they will replace the trim. I am very concerned about my sub floor , vinyl floor, and the water that went into my air ducts. I am very upset to why they will not fix it right. It is still under warranty. Any suggestions

Thanks

Cindy
