Hi V., I'm assuming that the seating area for the table folds out into a small bed, so would you or your husband consider sleeping there while the other sleeps in the cab over section with your son? I'm probably way off base here and the table area won't work for an adult. If so, forgive me for being obvious. Do you plan on using the table and seating area for eating on? We never do. It's always so cramped. We always eat outside. If you plan on eating outside, you could make that space into your son's personal playpen/bed. Just get some plywood and screws and attach the plywood across the opening of the seating area. You can buy fresh and clean foam rubber from Joann Fabrics or Fred Meyer (to name a few stores that carry foam rubber for camper mattresses) They cost about $15 for a twin size piece. Just cover the foam rubber with a fitted sheet and you've got a nifty little bed. If you need to cut the foam rubber to size, those electric knives that some people use for carving turkeys and other roasts work great on foam rubber. So does any serrated edged knife, but electric goes quicker. Oh ya, be sure to buy a little battery operated smoke detector and screw it into the ceiling of your camper. One of my closest friends is a fire fighter and she tells me that travel trailers, campers and RV's can burn to the ground in just a couple minutes. We have one in ours and I sleep great knowing it's there. Ok, so maybe this wasn't the help you needed, but I hope I helped anyway. Have fun camping!
