I did not mount either of them to the wall. I ended up using 3m Command hooks (metal finish), that way no holes and we can move them around as needed. I did put a towel rack that hangs on the inside of the door.
there are studs...but obviously the lauan interior wall board could hinder a stud finder...unless you use a magnetic one to find the staple points. I own both, not sure which one I like better.
