Al, Not knowing how your air system is plumbed, if your aux air is connected to your chassis air, the leaks on your Isrri seat could be pulling the system down overnite. Sometimes the converters (Marathon does) connect their Aux air system to Prevost's chassis air system through a manual gate valve. If that valve is open it could cause the Chassis air gages (brakes) to leak down to 40 or 45 overnite. So, if you have that valve, you can close it to help isolate the location of the leak.
