Help please, the drivers rear of my coach starts to drop overnight when parked. I have a 1998 40ft Affinity. I started trying to correct my problem by replacing all the air bags, and I replaced the drivers rear height control valve. I still get drop only on the drivers rear side. I know I must still have a air leak some where, what else could it be in this ride height system? Whats interesting is that it seems to be isolated just to the drivers side. Does any of the air tanks have an effect on this? I don't fully understand the air system, but can someone answer me, do I have three air tanks, one main tank form the engine compressor, which then supplies the two individual tanks for the rear and front, I am assuming for the service brakes and/or air bags. What tank or tanks does the air bags get there air supply from? Where is the location of the air tanks, I have found two tanks up front above my front axle, is there anymore tanks? Second question is: How does the HWH self leveling system work when engine is off, I hear my front 12 volt compressor run leveling the bags when I am parked engine off. Does the 12 volt compressor share air with my service brake tanks or is it on its own separate system. Is the ride height control valves on a totally separate system? I appreciate your responses, I know its time consuming. Thanks John

If you have the original manuals, you should find a diagram for the air system plumbing in them.
My rig has two tanks with a needle indicator for each on the dash. Their description is also in the CC manual. The leveling system is supported by the front tank I recall.
If you cannot hear the leak, have you tried spraying soapy water on the air lines near the rear driver side to observe any bubbles that result?
