Dinette Collapse!
We had the dinette in our 21C made into bed mode. I had scooted to the edge to get off and the table collapsed. (I weigh 167 pounds, or about 76 Kg.) The 1X2 cleat that supports the tabletop came away from the little knee wall. The screws scratched the wall on the way down, and made 3 puncture holes in the vinyl flooring.
Analysis: after going through the 1X2, then the 1/16" plywood, the remaining screws' threads were sunk into the interior softwood 1X2 by about a whopping 1/4 inch. I have no engineering degree, but know that this was not nearly enough to support the weight of two sleepers.
Solution: drill out the holes and put 1/4-20 carriage bolts in place of the six insufficient wood screws. Inside the seats was affixed a flat washer and nylon lock nut on each bolt. (I probably didn't need lock nuts, but already had them.)
Now I could jump up and down on the table if I was so inclined (and there was ceiling clearance).
