Chuck,

This might (or might not) be what is happening. On my coach, I had newish Goodyear airbags on the drive and tag axles. When ever I moved the coach at slow speed into an uneven parking space, the coach would occasionally just decide to vent all the air out of the rear bags. Normally on one side (but not always the same side).

There is a post about this somewhere on here...but I cannot find it.

Anyway, Richard and I fought the battle for several days. Take the bag out...take it apart...put it back in...see what happens. We never did figure it out but we suspected that the Goodyear air springs that were on my coach were the issue.

It happened again last year when I was idling in the alley at Newell. They had Firestone air springs in stock so I had them changed. So far a year later it has not happened again.

The design of the Firestone air spring seems more robust than the Goodyear. (All my air springs were fairly new and several have been replaced even though they did not have any signs of cracking).

If it happens again....make sure the e-brake is on and listen between the drive and tag tires and see if it is an air spring leaking. My bet it is.

For what its worth.
Cheers,
Bill
