We are in Blairsville GA at a nice park for a week now. I have been having air leveling issues all week, but did not seem major. Now they seem to be getting more severe. I am thinking the drivers side rear has a big leak or relief valve stuck open. I just tried to bring the coach to normal height via running the engine in travel mode with slides still deployed. The drivers side rear corner barely lifted off the wheels while the rest of the coach raised to travel height. I decided to dump all the air. The dump light kept flashing so I hit travel and then shut the engine before it could inflate again. We are leaning to the drivers side a bit, but at least the bode door will operate correctly, it has not many times this week until I releveled. 

At this point I am not sure the coach is drivable because the drivers rear is sitting on the tires. Maybe retracting the slides would change that but I don't think so. I don't have any jacks or blocks to get under the coach. 

Am I hurting the coach sitting with all the air released? 
Do I need to call Newell after hours or can this wait till Monday?
Any suggestions appreciated
