Jon,

Thanks for the thoughtful analysis. I really appreciate it.

I think I caught the system venting with the key off and not in auto level the other day. The venting was between the drive and tag axles on passenger side.

I am at the factory and will be on the pit tomorrow for a non related issue tomorrow (I think). If so, I will put the coach in travel, dump some air and see I can repeat the problem. To add to the description. If you look at the graphs, it does not take long at all to lose all the air in the bags when the problem is present. I am hoping for a little luck in being able to hear the leak when I can get under the coach.

If that does not work, I will start measuring air pressures at the six pack.
