Very interesting thread. Salute to those that contributed to it. Chuck you did  great job of trying to remotely diagnose a difficult
issue we all have faced.
Gary one thing more to check is the output of your 12v compressor and for leaks there. I had several big leaks around the compressor T that had the high pressure release valve. Also at the bottom of the plastic bowl there's a O ring that was bad on mine. Still trying to hunt down all my leaks. Very frustrating. I would replace all the air bags on the coach if that is found to be the problem. if one is bad....
Good luck and hope you figure it out.
Also get the 6 pack rebuild kits from Tom.

Update:
Airbag was supposedly ordered Friday and should have been here today. They were not in shipment so they called and found out it had not been processed for delivery which means bag won't be here until Wednesday.  :facepalm:
This is a nice campground except for the deer fly's they will eat you alive bug spray or not.
Enjoy 😍

New airbag installed and working. Have driven about 500 mi and everything is as it should be.
The gauge I installed at the airbag reads 68 psi when in travel position.
Thanks 🙏 to everyone for all the help and knowledge.
Side note shouldn't there be a stop to keep tire from rubbing wheel well?)

Perhaps there should be a stop...but there isn't one.  Just one of those Foretravel oddities.

Nearly every older coach you look at will have some rub marks in the top of the rear wheel wells.

Since air bag did have a bad leak, you were not able to hear it?

My wheel wells were worn threw and I was going to make stops but after I repaired them I use
a graphite mix with the epoxy from West Systems and there is no sign of wear so I haven't bothered.

I find that fact to be interesting.  Don't worry - I'm not saying there is anything wrong with what you say - just interesting.  I have always assumed that it required higher pressure than that to raise the rear of the coach...since it is so heavy.  But, apparently not!

The HWH Leveling System Textbook says:
"Although it may vary between different vehicles, it normally takes at least 60 psi to start lifting a vehicle. Most vehicles will require 90 psi to obtain maximum lift. Some may require up to 130 psi to obtain maximum lift."

Of course, that's talking about "maximum lift", not travel height.  Also, perhaps that comment pertains more to later model heavier coaches.  Our old GVs are relatively light compared to Unicoaches.

Not having stop before tire rubbing Seems  odd.
Will check pressure again tomorrow. Old eyes may have deceived me. 😲

Not with engine running.

As long as you turn off the engine with air pressure over 100 PSI, and suspension is in TRAVEL MODE, you should be able to hear any massive leak.

How quickly does pressure drop under the above conditions?

With old airbag with leak it would only rise about 1in. From wheel well to tire. As soon as engine turned off would settle down on tire. No time to listen for leaks.

Rechecked gauge this morning. Gauge indicated 70 psi with RV raised to travel height.
Think this adventure is over.
Thanks everyone!
