Ok Supercub,
First I want to appologise for not thinking straight when answering your question. I was stuck on the leveling operation and, how it works pertaining to the jacks AND THE AIR BAGS. Well, what I completely forgot was, the situation that I have on a regular basis. And that situation is, if I park the coach and simply don't dump the bags, and walk away from it, my system leaks air.
So, if I park it with full tanks and full pressure, it's at 130 psi. But, in a few days, it's sitting at 100. And, in a couple days more, it's sitting at 80.
But, if I get into the coach and fire the big beast up, YES it will inflate the bags automatically. That's because I've not triggered it to dump them in the first place. Now, what I've never done is, dump them on purpose, leave. Then, come back a few days later when it's had time to leak down and, see if it will fill automatically without me hitting the store button. The reason is, I cannot dump the bags without turning on the HWH system in the first place.
So, in the situation I just explained, yes, it will fill automatically.
