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.

The gauge I installed at the airbag reads 68 psi when in travel position.
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. 😲

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!
