I'll probably copy this. How (and where) did you attach it?
It sounds more complicated then it really is.. So after figuring out where (height wise) I wanted it. I applied tape on the wall and drew a line in the center of the tape, drilled 3 equally spaced holes through the wall into the closets on both sides of the bed. Because the walls aren't the strongest I put a doubler in each closet. Lined up the shelf and put in 3, 3in. screws each side. I'll hide the doubler soon when I make a small set of shelves in the closet. BTW we just returned from a 4 day camping trip. The shelf worked just fine.
