I know on my MH it has autoleveler and some time it will lift the tires off the ground before it stop. I have found that sometimes, if I lower it and re-level, it will stop with the tires still on the ground. Other time the leveler will stop at level but with not enough load on the jacks to stop the bouncing when moving in the MH so I have to over ride the auto-control and extend the jack a little more and a wheel will come off the ground. We all have our own reasons why we do things we do.
