I've not seen it addressed, so I am asking: has anyone tried to fill the gap above the bathroom door? I am trying to think of ways to close it off without harming the walls or ceiling, but can't think...
We placed a metal bar that fits over closet doors which has hooks on it, turned it to the outside and hang dishtowels on it for kitchen use. You could hang other things on the hooks such as jackets, etc. Had no trouble with the bar sliding off the top of the door when RV is in motion.
