I have a 2014 Big horn and we noticed this summer that the whole right side half way in the middle to the bottom has all delayed. We took it back to where we bought it and they did test after test and realized there was no water damage to cause it. So they contacted heartland and they want the the rv place to cut a hole and send it to them but are saying they will not be responsible for it. I dont know what to do please help. Heartland does not want to stand behind there rv.
