Ok, no experience with that, BUT the systems share some common operating concepts.

Couple of questions for you. If you look underneath that panel, are those knobs hooked to air lines or electrical wiring?
If you open the passenger side engine door, do you see an octopus of valves mounted on the forward wall? If so, can you post pics of that.


I am going to make some assumptions, and that is dangerous. Please confirm when you try this.
I believe if you pull the red knob up, it will enable you to add air to the air bags, and if you push it down it will enable you to let air out of the air bags.

So, for grins pull the knob up, and activate the two front buttons. Does the front of the coach raise? By the way, the engine must be running or you must be hooked to shop air for this to work, otherwise you won't have enough air pressure to do anything.
