Hmmmm, it is possible that there are two confounding things going on. The first is why is the front dropping. I would highly recommend as Tom suggested that you build the air system tester, and isolate the front air bags from the six pack. That will tell you if the leak is in the air bags/tanks/connections OR in the six pack.

The second issue is the behavior of the HWH computer. I can't help there, cause I turn mine off. It does nutty stuff from time to time if left in relevel mode. One thing to be aware of is that the HWH computers read an air pressure from the sixpack manifold to keep the coach from pancaking on the air bags. Those sensors have been disconnected on many Newells which complicates the autoleveling algorithm.
