After one attampt to use the automatic levellers, I decided I could do a much better job.
My procedure (it's an older rig) is to power the system up and extend all four jacks until the feet are just touching. Since the control panel does "all", "left pair", "right pair", "front pair" and "back pair", getting them all just touching can be an interesting exercise.
Once that's achieved, I then go for the least amount of extension that will get the rig level. With an arthritic dog who has trouble with the steps, the closer the bottom step is to the ground, the better. She's not with use any more (see sig.), but we still use the procedure we developed for her benefit.
We have been at a couple of sites where the pad was so ridiculously out of level, we asked for a different site. In both cases, the CG wasn't too busy and they could accommodate.
I haven't used the CG reporting function on the forum. Do people report CGs with pads that are ridiculously out of level?
FYI, the Larrabee State Park, just south of Bellingham,WA, has a problem with sites that are both longitudinally and laterally very much off level and it's difficult to get the rig level without very large differential displacements of the leveller actuators. We ended up with about 19" from the ground to the first step of our extending steps.
We won't be going there again.
