you're right--the door is too thin. The only place that the bathroom door (or any cabinet door for that matter in this trailer) has any solid wood is along all the edges. We put an over the door towel rack on the inside of our bathroom door, but it tended to slide around and rattle too much when the door was opening and closing, that I put a couple of small screws at the top of the door to hold it in place. As far as the TP holder, the easiest place to put it so it was easy to get to was there by the sink--fortunately there is that one strip of solid wood. Very accessible when needed, but stays dry (we have little grandchildren that sometimes camp with us--not always very neat with water!).
