I understand. Here on the east coast, we hardly ever camp without hook-ups or generators. At our races, all you hear are generators running all night long.
So for us, the residential fridge is great. But I certainly understand your frustration for what you folks like to do with them.
Back to the OP. 6 point leveling is awesome. As others have said, hit the button and back up. Let it do its thing. But like YnotTurbo, I like to use some homemade blocks underneath each leg. My tires are 235/85-16 so they are a little taller than stock. The blocks keep the legs from extending as far and it appears to be more stable.
One weekend we were camping with friends at a lake. The sites were terribly slanted. The 6 point leveling had to pick up all three right side tires off the ground to get level. It did so and we stayed like that all weekend long. It was amazingly stable and didn't budge the whole time.
