Well, I installed new bags and re plumbed all the air lines to them. I removed the leveling valves and installed manual valves to level the bus while camping(as described here). I am using the front bag supply to feed all bags now,and sealed the old rear bag supplies. I also added an aux compressor to maintain pressure while parked.
I did have one issue, even though I installed check valve to prevent my aux comp from dumping back into system, the air gauge was showing 70 lbs steady. Is there any other avenue for the air to get back into the main system?
Mike, your link to how you made your air bag setup is not active on my computer. Can you check it please? I'd like to read how you engineered yours.
Thanks!
