My 3400RL has the window in the super slide so you could reach the handle and pull it back from the door if you had to. Why not just take a wire tie when camping in one place for awhile and put it around the top fitting to keep handle in the "out" position. When you are ready to hook up and move simply cut the tie. I would think that any idiot that came by and tried to lift the handle up and move it into the closed position would have to take a minute or two to figure why it wasn't moving.
