I can set it up before I go to bed or as we set up the camper once we get to the camp site. It takes me about 5-10 mins to place the shelf up, pull out the CPAP, connect the hose/mask and hang the battery pack up.
I went as cheap and simple. The poles are 3/4 PVC I had sitting around, which I painted afterwards to make it look fairly nice. I went with some simple snap clips from the hardware store and screwed them to the bottom. I used some oversized PVC T-fittings wedged between the mattress and back wall to keep the bottom from moving around.
I do like some of the shelving ideas used in this thread, look at the second block.
