Dennis, I was reading your post again…the air gauges you refer to are for the air brakes, front and rear. An air leak in your suspension system should not drain air from the air brake system as safety systems are built in to prevent that from happening. I’m not sure where the leak would be that would allow both tanks (front & rear) to drain down at idle like you describe but that is a major leak and I don’t think I would drive the coach in that condition.
