Need more info....but in the meantime, dump the air bags and engage levelers. If auto levelers, let them run through their setup and leveling. Once done, start engine, retract levelers (Travel Mode) and look at the 4 wheel positions and see if the coach is lifting. Sometimes they just glitch, especially if you interrupt the leveling procedure.
