I'd be interested in how well these work also. I sleep rather lightly and am on the front bunk in our 233S. One kid on the back bunk and the other on the side bunk. If either of them roll over during the night, I can feel it. One thing that helped a little it bit is my setup routine:
level the trailer side to side.
unhook from truck
level front to back
drop side bunk and extend slideout
drop corner stabilizers
drop front and rear bunks.
That side bunk and slideout all on one side of the trailer really changes the balance of weight side to side. So I think putting the stab jacks down after those are out lets them get set into a better position.
