Black marks on ceiling
I saw a post on another forum by a Montana owner who had black marks on the ceiling and didn't know what caused them. We have those same marks which seem to be in line with the ceiling struts. They go all the way across the ceiling and also on the slide ceiling. I've washed them off but their coming back again. Anybody know what causes these and is there any way to prevent them? Some folks on the other forum said they were caused by poor insulation or improperly installed vapor barrier. Any truth to that?
