Richard, yes I have been chasing this leak since late summer (August), but I travel for work and haven't had as much time as I would like to devote to the coach. I have 75psi on both supply and brake, but I have an external air compressor that I will hook up to the air coupler in my engine compartment. I wasn't sure if that coupler had an inline check valve that would prevent back charging that air line. I also have a 30' air hose to isolate the compressor. Then I will listen with all the bay doors open and go under the coach as well. The coach is currently sitting on 4-22 ton jack stands for safety. I  will then conduct the tests and report back.

Thank you,
Jeff
