there are soooo many air fittings, lines, tanks and devices in the system that a bunch of very small leaks can cause a fast one. fittings can leak, airvalves for various things like the dumps or doors or slides for bay fridges or bbqs are culprits.
air leaks can take a lot of time and at 100 plus bucks an hour you can rack up quite a bill.
start at the obvious places where things are exposed and spray with soapy solution. i use 100% kids bubbles that you get at the dollar store for a buck a pint. it has glycerin or something in it that makes nice bubbles with a spray bottle.
the infinicon whisper is nice and i have one too, but it is an acquired skill to use accurately.
as for getting under the coach. this may be redneck, but if you have some 2x10's you can drive the coach up on a few of them to raise it 3 or more inches. then raise it up using the leveling system and then block it with 22 ton jackstands or big blocks of wood. if your are skinny, you can do it without driving it up on things, but by lifting it up and then blocking or putting jackstands underneath. make sure if yo get underneath, you do have it supported somehow. 55k lbs can flatten you pretty quickly and completely. ask the witch in the wizard of oz that the house fell on.
the real thing about airleaks, and electrical problems is to break it into pieces. isolate into small chunks. btw, newell says i believe that if your compressor comes on once every 45min, that is acceptable. mine is down to only a few times in an 8 hour period. but i have spent a ton of time fixing leaks. that said, i still have an front drivers airbag that goes down in a day. i am going to replace the airbag as i we have looked at everything else.
another way that can seep your supply system down is your brakes. the airbrake system is designed so that if there is a leak in the brake air system, it will steal air from the coach supply air system. if your two brake air gauges are going down quickly as well, then there is something in your brakes. or the check valves for each of your two brake tanks are bad.
there is lots of material on the forum about finding, isolating and fixing air leaks.
