It would help to know what is next to the bed now. If it's an outside wall, that limits your options, but a closet wall for instance, opens up the possibilities for an enclosure of some sort. I don't have any photos of it, but on a previous RV with no nightstand on my side of the bed, I cut an opening and inserted a square sided plastic storage bin I found at a dollar store. The rim was perfect for attaching it with several small wood screws, and some wood trim finished it off nicely and added a small lip at the front. A piece of shelf liner kept my "stuff" from sliding around.
