Do air bags air up at start up of my class A. Beaver mtr hm?

Thank you for your replies. So the airbags air up upon starting the engine than you retract the levelors. When you store the coach does it hurt to have air in the bags or should it be stored with the bags deflated? What is the reasoning on this? My coach has 3 leveling jacks two in the back one in the front. Thank you for your replies.
