I had an Aerolite Trailer once with this type dinette table. I left it in the raised position while on a long trip. A couple of the hardware screws pulled away from the wall a bit. I replaced the factory installed screws with Expanding Hollow Wall Anchor Screws
. These are tuff screws and won't pull away.
Remember, the inside wall panels are 1/4" thick, foam center. There aren't many studs in place and I doubt you'll run into any wiring in that area.
