Last year I replaced all of the rear air bags and control valves.  Recently I replace the front air bags and one control valve, and stopped all under coach air leaks.  During 48 hours, the 110 volt compressor ran 1.8 hours in level mode with the system on automatic.  Assuming the compressor runs for 10 minutes each time, it runs about every 4.5 hours with two people living aboard.  It seems to me that I do not have any large air leaks, or should I expect something better.
