Ellen & David,
I have a good understanding of how the HWH leveling system works. The reason I commented on your post was because you mentioned some features of which I was not aware, namely:
"you have around 6 air pressure sensors.......on the air bags.....to tell HWH System bags are inflated."
I was curious about this statement, because all the HWH leveling systems I have seen only have 3 air pressure switches - 2 in the front and one in the rear. They are not located on the air bags - they are located on the 6-pack manifolds. And, the switches have no way of knowing whether or not the air bags are inflated. They only know what the pressure is in the manifold to which they are attached.
Reading your post, I thought the HWH Series 2000 system might have some features that differed from the earlier systems. That is why I asked. After looking at the manual, as you suggested, I see the 2000 Series is basically the same as earlier iterations, but there are differences. One big difference is the addition of two "extra" pressure switches on the rear 6-pack manifold. Plus, if the coach has a tag axle, then there are 2 more pressure switches on the tag manifold, giving you a possible grand total of 7!
Makes me glad the leveling system on our old coach is so (relatively) simple.
