Bingo! I had dismissed the valve in that compartment because the lines were black, not blue. Pressure gauge showing 17 psi, valve and regulator - now I get it. When turned off, the leak stops. Pretty sure it's the seal now. Will be moving the coach to Phoenix in a couple of weeks and will pursue a correct fix then. Thanks everyone for your help.
