I just got the 16' camper this spring, then found a 13' a month later. We'd been working on the 13' and the 16' was closed up. It didn't have mold when we got it and I know the prior owner was just storing it outside as well. Like many places, we've been having a lot of rain lately and I would check it continually for
leaks. None that I see. Really disappointed to find it started all over the ceiling and concerned it will be an ongoing issue. I used Kaboom on the 13' for cleanup and it works well for mold removal, but made me sick. I do use quality essential oils and will be diffusing tea tree oil inside the camper. I really want to avoid this happening again.
