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

with the jacks up and the air tanks empty the air bags will start airing up at about 90 psi, there is a check valve in the system that shuts the air to the bags off when the tank pressure drops below 90 psi in the event of a bag rupture. When the system is aired up and you turn on the leveling system on the air bags will deflate until the jacks are raised back up, then they will reinflate automatically.
