Jon,

Thanks for the great explanation. Let me first say that patience is NOT one of my spiritual gifts. This is an ongoing struggle.

My conversation with Luis included moisture from the aux air system. My small aux air compressor has no dryer, probably like most of our coaches. He taught / showed me where to drain this system. Most likely when I tried to raise my bus' front end, I did not notice any change because the air way was mostly blocked, and I did not hold the UP switch long enough.

BTW we can camp without the aux air compressor on, because of manual pocket doors, electric toilet, etc. The only time I run it is before starting the engine to bring up the small air bag on the belts. And I have never drained it since we owned the bus (4 years next month). But I will now!!
