The PPV should be underneath the coach inside the frame rails at approximately where the rear wheels are. Bad news is that you will have to raise coach to get to it. When mine went bad, the mechanic that came to the house rigged up at fitting to apply air to the discharge line on the 120V compressor. This supplied air to the "Supply " side of the air system. We were able to raise the coach with this air supply. Be sure to crib the coach properly before going underneath it. Most truck roadside mechanics should be able to fix this for you. Alsoon mine it took a day to get parts in.
