Long story short, it was a long story, on the second day of my trip to Memphis my supply tank pressure started dropping and kicked the engine air compressor on about every 6-8 minutes, far more frequently than it had been. I isolated the leak to the uses downstream from the ball valve that isolates the front air distribution block. I finally eliminated the leak by cycling the step cover. Since the cover had not moved in the 3 years I've owned the coach that may have allowed some seals to take a leaking set. I will need to cycle all the air driven stuff now and again to keep the seals functional. Just thought I'd pass on a weird experience.
