2010 Monaco Diplomat 42 SKQ On September 19 we stopped at Portal RV. The site was very level and I did not put the jacks down nor did I dump any air. We had full hook ups with 50 amp service. On September 27 when I woke up the MH was leaning significantly to the passenger side. When I started the engine, we were leaving that day, the low air alarm sounded and I had low air front and back. We spent September 27 to Oct.2 at Mesa Verde NP Dry camping but the jacks were down. Had low air upon startup. Arrived in Grants NM Oct. 2 (waiting for MI at Balloon Fiesta Oct.9) On Oct. 5 woke up, MH leaning passenger side again, site was level so jacks were not down. Started engine, low air alarm, refilled then lowered jacks. We are again at a site with full HKU. Each time the ambient temperatures were near or below freezing. Where do I start trouble shooting?

I would first look for a small air leak in a airbag on the leaning side.

Also if your coach does not have air leveling, that is normal for the system to air down after some time. Sometimes it leaks faster than other times based on the position of the coach. Mine leaks down in about one week on average. Sometimes longer.

Could be that one of you needs to loose some weight.

ouch........! That's a hard stab........
I would air it up and then with your wifes help put all 4 jacks down and stop them just before they hit the ground, if they hit and start to lift the Coach the air system will dump just a bit(jacks down just for safety) then go under and use a soapy spray bottle and your ears and see if you can locate your problem. Good luck......
