I was having some work done on my coach when I overheard the service manager tell another customer that he had lowered the airbag pressure on his coach to give him a softer, less jarring ride. Have any of you heard of this? Or had it done to your coach?

Not sure about the coach he was talking about but if you lower the pressure the coach will sit lower.
What year coach do you e?
Not possible to lower air bag pressure on any air suspension coach I know of without lowering RIDE HEIGHT. A dangerous solution-- hard on suspension and drive line!
Would love to know what coach and who in the world recommended this!
Maybe he was talking about tag axle air bag pressure, some coaches have an adjustable regulator, so you can load or unload the weight the tag bears.
Didn't ask the service manager because it would be somewhat embarrassing to admit I was eavesdropping on his phone conversation.
Could be, but changing tag axle pressure would have very little effect on ride quality and if lowered, would materially overload the drive axle and under-load the steer axle.
We have Firestone air bags on my Excursion front leaf springs,lowering pressure does lower the truck,could be what he heard.
Ya, AIR-OVER ________ is very different than air suspension!
But isn't it possible that if tag pressure was too high, weight would be transferred to the front axle, perhaps overloading it, and front bag pressures would increase causing a rough ride, and if too high, would also unload drive axle and perhaps overload tag axle causing a problem there too?
Absolutely.
Incorrect tag PSI/load can either under or over load the other axles.
Ideal is to have the same percent of GAWR on each axle.
It really takes scales to properly set this-- been there, done that!
Surely the air pressure in the air bags is directly related to the weight supported by the air bags and the only way to adjust the ride height is by adjusting the ride height valves.
