Michael, to answer you question. It will cycle from 90 to 115 in about one minute, very quickly. You can see the needle drop and see the needle come back up. When engine is not running the 110 comp. will cycle from about 75 cut on to about 95 cut off. When engine running the two brake needles stay at about 110 lbs unless I apply the brakes then the white needle will drop but quickly come back up.

Steve the supply gauge will stay at the pressure it was when the engine is cut off. Yesterday it was at 110 lbs and stayed there. Did not move while I was unloading the coach. Probably 10 minutes. Of course it will slowly go down until it is about 75 then the 110 cuts in in an hour or so. There should not be any or a very little water in the rear tank. I pulled the lanyard on the rear tank, the only tank that has a lanyard, before I left for home, a little over 200 miles. Not much water came out. Drained the other front tanks and the small tank in the rear wheel well before I left.
Thinking back, one thing I do remember is yesterday when we pull over for lunch I did not have the 110 comp. on because I was on inverter and the supple gauge was on zero when I cranked the engine after being there for about 30 minutes. I thought that was strange at the time. I was in ride height. Now when I put the coach up yesterday I raised the coach up as high as it would go and blocked it. Maybe if I left it in ride height things would have been different. Maybe it is the six pack. I'm going to change the oil before my next trip and I will run the engine to warm up the oil and after I've changed the oil I will remove the blocks crank the engine and bring it down to ride height and do some checking at the six packs, etc. I doubt one would be able to hear a leak with the engine ruining but I will have my wife give it a try. Any other suggestion will be appreciated.
