Automatic leveling system on Mercedes Sprinter 3500 chassis

Another vote for the yellow lego blocks. We have only had to use them a few times and it took about 5 minutes to get them out and level the rv. There is some side to side motion in the rv without levelers, but we used to get some in our diesel pusher with levelers. We also have a bubble leveler on a small shelf/cup holder behind the drivers seat so that I can see how level we are before I shut down the engine.
