We had our 2012 repaired just before Labor Day. It IS a known design flaw. That's why they're no longer using this floor system, at least in Rockwood models. New floors are now 5/8" tongue and groove. No more 1/4" luan plywood sandwiched around foam. Unfortunately, they can't retrofit the new floor system to older models. I asked during our factory tour. I think we'll start thinking about a new model before our floor starts to get spongy again.
