I can't find any air leaks.  Loosing about a pound a minute when parked. 110volt compressor cuts in at 70 and cuts out at 90. Runs about 5 to 10 mins every 20 mins.  I have ruled out the air bags and the leveling, stays level with the leveling system off.  Only 3 air powered items, the toilet, drivers seat and an interior sliding pocket door.  Soapy watered everything I could find and I do not see or hear any leaks.  

Could a 110v compressor be set up only on the auxiliary side of the air system rather that the entire bus air system?
