Update On Air System Issues
Curt: I found a leak on the Pressure Protection Valve
http://www.ryderfleetproducts.com/cgi- bin/ryderfp/products/srm/oid/48389/erm/product_detail.jsp on top of my wet tank...Bill Pape told me to check the 4 cap screws on the valve and shure enough after tightening the 4 bolts the leakdown rate is greatly reduced. My air throttle still works immediately after 24 hrs but chasing leaks is still an ongoing ordeal.

When I bought the coach 3-1/2 years ago it was leaking 60 > pounds in 20 minutes. I monitor this by the holding tank dump station > pressure gauge.
