There HAS to be more to this story than the OP is sharing. When the OP went thru the unit when he purchased it and had his walk thru, did you not see this damage? IF there was damage, it should have been noted at that time. If you had no walk thru, THAT IS YOUR FAULT. Now, Heartland has a BAD reputation among Dealers. Numerous Dealers in our area dropped Heartland due to this type problem. Luckily, we never fell for carrying Heartland. Unless you can talk to Heartland and get them to step up, you will probably have to get a Lawyer. It may also be, (very common), that your Dealer has already been paid to fix the problem and either did not fix it or did a poor job and the problem came back. Which is why a OEM will deny warranty. I would ask Heartland direct if they have already paid for this fix on your RV. Doug
