I'm a bit late entering into this discussion about the flaking substandard upholstery material, but it is very relevant to us. We just purchased (10/2020) a 2011 3100. The upholstery was BEGINNING to looked a little over used (the rest of the coach is perfect) when we bought it. The sellers, gave us a $2000 concession to cover the upholstery. We spent 12 days on the return trip home. We are NOT tough on furniture, but it is amazing to see how much this stuff fell apart!! We thought when we bought the coach that we could take our time getting the reupholstery taken care of, but NOW, it is such an eyesore, this must be addressed immediately. The dinette, and both front cab seats as well as some of the wall coverings are looking very poorly. Sad that PC hasn't stepped up to fix this issue. I called the factory and was told that there are no "pre-made" replacements to the dinettes (heck, they're just stapled to the plywood bases) and they estimated that the repairs would cost us $2000.
