We are in Jackson California. As we're leaving the RV park I noticed I have low air pressure. Now the brakes seem to be set coach won't move. Does anyone know of any easy checks or fixes I should check as I wait for help? This is a 1974 Newell with the 1160 cat Allison Transmission.
either your engine compressor is not working or you have a massive leak
did it air up ok when you got ready to go?

Check your air dryer purge valve. Usually on the bottom of the air dryer.
When they fail, you won't be able to build any air pressure & you can't hear the leak due to the noise the engine is making.
Thanks Everyone. Good news is it ended well. We made it home.
I borrowed a small air compressor from Jackson Rancheria RV Park maintenance guys (this is one of the best small RV parks you will ever stay at in California, google it). As I aired up the coach I noticed air leaking fast from an unloader valve or governor (I don’t really know the terms) under the coach by the rear air tank. So with the coach supported I slid under the coach and tapped it with a hammer. It quit leaking, well almost quit. Anyway the compressor aired the coach up to 120 psi and then when I started the engine the coach’s compressor was able to maintain pressure between 90 – 120 psi all the way home. I will be taking it in to

You were all great with your suggestions and offers of phone help. By the time I saw your replies I had already received a phone call from a friend in another RV group. He is the one who suggested I find a compressor and try to air the coach up.
What did we do before online forums?
Thanks to you all!
If the valve is attached to the bottom of the rear air tank it would be an automatic drain valve that dumps any liquid that collects in that tank.
