Our wall is a short one and nothing could be put over it to hide the area after its fixed. We would have to see if Coachmen has wallpaper we can put over it that matches. Or maybe no one will actually notice it! Thank you.Re: How to remove/kill mold behind RV walls?Good Morning, I am new to this website. I was watching a video on an RV for sale and the salesman showed a wall behind a chair that had "bumps" under the wallpaper. He said it would appear that it was a "factory issue" and not from a leak. And that it was MOLD SPORES under the wallpaper. We have a 2016 Coachman Leprechaun that has some of those "bumps" between the bed and the wall with an emergency window above. We didn't see them at first, and then after we had it awhile I noticed them and thought they were just bumps on the wood before they covered it with paper. They appear to be spreading, and now that I watched that video last night I am very concerned that it could be MOLD SPORES. What do I do??
