I have a 2013 landmark San Antonio which I love but know the roof wood under the rubber roof is buckling up about an 1" or more in some spots . There is no water damage in the coach and I always maintain the roof and the caulking . Doing some research its seems it is the Luan wood that the factory uses on the roof and it buckels beacuse the factory does not attach it in to many areas .It is only three years old but I am the second owner the and factory service rep said that they will not do anything about it. I even ask if they could help out if I bring it to the factory maybe with the cost and he said basically they will not and to busy also. I really like the Rv and in the past with my other heartland the factory always helped out . Not sure what to do I guess I will have to get some prices and see what I can do . I have never head of a factory saying that the warranty only goes with the first owner. My wife and I bought this coach so we could live in it while we are doing volunteer work on the east coast for a couple of years . This is really going to hurt the pocket book if we can even afford it. I wish heartland would help out some being that it is a factory defect .
