ok,
to find leaks is an artform. listening for big ones....sparying windex or soapy water to find bubbles, using various leak detectors to listen....everyone has their ways.
i have found them all the ways.
1. i have replace a couple of the small air dryers/water seperators that were leaking
2. loose connections
3. solenoids at manifolds.
4. my engine air dryer was leaking
5. a couple of the brake porportioning valves for the tag were leaking.
6. my emergency parking brake was leaking under the dash at the seal on the push pull rod.

Add airbags to the list.
When I replaced my rear airbags, I suddenly found that both of my air gauges were reading about 50 higher than they were. Also, my air compressor runs far less frequently than it did. I did not ever hear a leak around airbags nor did I do a windex inspection...but the circumstantial evidence points to my airbags as one of the guilty parties.

Add: Check all the welds on your air tanks. If the tanks are not drained regularly it is common for pin holes to develop in the welds. I've repaired a couple using JB Weld.

If you take a look at my Gallery, you will see the welded repairs on pinholes in my upper brake air tank.

How many tanks are there? I know of the one up front by the compressor and gen blower. Mine has a device that I push a button to drain regularly. Are there others that I need to be draining? When they installed the toad Air Force One system, I saw a tank in a rear compartment on passenger side, but I don't have one of those water draining devices on it.

For your vintage coach, with a tank in the genset blower compartment you should have 11.

11??? Oh my, I guess I have some serious research to learn the entire air systems on this coach... I am not sure whether to laugh or cry

Some of those tanks will be built into the frame and may be difficult to locate. After blocking the coach, crawl around underneath and look for either a plug or drain valve.
