Dean's description of the HWH automatic leveling process is right on. My leveling system is tight and will hold air for months with the compressor off. The air pressure for everything else will go to 0 but the air bags keep my coach level. If you leave the HWH system "on", the HWH automatic leveling system will check its balance every 15 minutes or so and readjust if necessary. If the 120VAC compressor is off and the HWH leveling system is "on", if may not be able to level the system after the air pressure drops. Since mine doesn't shift much, I typically turn my leveling system off after it has completed leveling whether I have the 120VAC compressor on or not. Your mileage may vary!
