Working through my Trillium 13 rebuild and am starting to think about the 'closet'. I'd like to add some form of shelving or drawers and am curious what others have done. I am NOT a carpenter, so building something is not in in my wheelhouse.
I build uprights and cross pieces out of white PVC pipe, and constructed a framework right in the closet. It's a snug fit so it doesn't move. Then plywood shelves were added, and after a trip, lips were added to the shelves.
