[Fulltiming]

Never had that happen but then I always turn my leveling system off after leveling so it doesn't recheck the level every 20 minutes or so. If the coach loses enough air in the suspension system when parked to need to relevel, the AC compressor may have trouble keeping up with the needed air. Raising the coach uses a LOT of air. Is the site you are in relatively level? Is any of the four corners of your coach drooping significantly (visually) after 24 hours?

I take it that everything was OK for the first 24 hours. After you manually shut off the level control, does the leveling system shut off as it should? If so, start the engine, build up full pressure, then turn on the HWH to auto level. Does it then level properly? If so, I would just keep turn the auto leveling off after the coach initially levels. If you have the same issue with full system air pressure, either your HWH brain isn't communicating with the level disc, or the system has just lost it's mind.
