Anyone know how rear air bags work

Generally you adjust the pressure to restore ride height to normal after applying a load to the vehicle such as hooking up a trailer.

You need to find out what kind you have. Some require a minimum pressure to avoid damage.

Please tell what is "normal" ?

Generally speaking, with airbags, if there is only ONE air fitting to feed both bags, when you go around curves, and the motor home leans, it will force air from one of the bags over to the other side. A lot of people feel it's better that each bag has it's own separate air line. In addition to preventing this, it allows you to put more air into one side or the other to adjust for side-to-side weight differences.

BTW, is there air in them now? How much? Is your motor home level?

It’s a 2013 Winnebago 26he Sunstar But they didn’t come on it

40+ years years ago my Dad had some on an old full sized Mercury (what a "boat" !). They worked great ! He had extension hoses that went out to the sides. The only issues was they recommended that you fill them BEFORE you placed a load on the vehicle. After loading, excess air was removed to get the ride height back to normal.
