When we bought our rig, the levellers went berserk when I first tried them in auto. The pairs kept chasing each other and the system almost got all four wheels off the ground.
When we got home, I parked on our almost level driveway, emptied the fridge and put a short surveyor's bubble level in the bottom of the fridge. I then carefully used the manual mode to get the rig as close to perfectly level as I could. After that, I stuck bubble levels in the fore/aft and left/right axes of the rig, close to the levelling system control panel.
At CGs, I pull in to the site and see how far off level we are. If it's ridiculous, I ask for a better site. If it's close, I might shuffle around for a few minutes to get close to level while still on the wheels. Once parked, I then use the manual mode to get as little jack extension as needed to get level. I figure I'm levelling to keep the fridge happy, not to get the load off the tires.
