I always use auto level as I think there is no more torsional movement than driving down the road. I would recalibrate the system using the longest level you have access to. This is also a good time to add a slight tilt so the A/C drip always comes off at the same place. I also do not allow the wheels to go off the ground when leveling. I use wooden blocks under the wheels if the site is too sloped or slanted. When working under a vehicle, one always uses jack stands to safely support the vehicle, never trusting the hydraulic jack that lifted the vehicle. Well the leveling system is hydraulic and I feel safer with the wheels touching terraferma.
