So a month ago, I bought a new to me 37QB and noticed that there are cracks on the outside where the bunkhouse slides come out. There is a crack on each side of the unit upper corners. I talked to the dealer since I have found other issues with it, and they told me that I bought as-is, but to bring it in and they will take a look at it. I am unsure how to fix it (if I can even do it) properly. My thoughts are that whatever I do, the cracks will reappear/get bigger. I am worried about water penetrating into the walls. I have been thinking that if all else fails to use clear epoxy and seal the cracks up. They are about an inch long at this point. I dont think Heartland will do anything for me since it is a 5-6 year old camper. Any advise, tips, tricks?
