We are considering purchasing a used 2009 Sundance 2900MK. We love everything about it and it seems well cared for. However, there are tears in the laminate that seem to result from the slide for the couch/dinette. Has anyone experienced this problem or have an explanation for it. We will have the dealer prep the unit and they are aware of our concerns with this issue. We have received a generous discount to repair the floor ourselves, as we suggested. We have purchased from them before and they are quite accommodating. Can you suggest any questions we should ask or things to look for before we finalize the deal?
