EricV,
Over the years I've attached hundreds of things to walls using this method I'll describe later. The RV walls are a bit different. They are usually 1/8" or 3/16" Luan or some type of man made plywood material. Are they strong enough to handle attaching a folding table? Yes!! If attached correctly.
Some of the RV manufacturers tell us that when attaching the heavier objects to walls they place thin metal plates in the wall during the manufacturing process to strengthen those attaching points.
When you look at the typical booth dinette the flat surface is supported on the aisle side by folding legs setting directly down onto the floor and the inside is setting on a wooden strip attached to the wall. The pressure is at right angles or straight down the wall and down the legs.
If you attached your wall support correctly and have your aisle legs the same as a booth dinette you'll have no trouble.
How to attach to the wall. I typically use the plastic, tapered round wall anchors. You drill the hole larger and when the screw is inserted it expands to hold the anchor in the wall. I first drill the larger hole and tap it into the hole with epoxy (5-minute) on it. Let that set up and then screw the sheet metal screws in also with epoxy.
If you use a piano hinge for your folding table just anchor a piece of nice wood to the wall using the method above then attach your hinge to the piece of wood with the legs folded and stored under it.
I have a 3/4" thick wooden shelf next to my drivers seat attached to the wall with 4 wall anchors. It's been there for 4 years and is just fine. I keep all my stuff like coffee, mugs, pens, food, gum, phone, water bottles, sunglasses, keys,remotes etc.
The most critical aspect of this install is to have the legs on the aisle side pointing straight down. If you used a triangle with the legs against the wall that changes the angle so it could pull away from the wall instead of at right angles. I think you get my drift.
