Rear air bags ... What psi should they be

After a 1/2 year of owning this new to me 2001 Fleetwood Flair 31A I just discovered two air nipples in the bay where my sewer and electrical are. There is a little plaque that states the air pressure must be maintained to a minimum amount, but that minimum amount of PSI is not stated. I put an air gauge to the nipples and both register zero psi. I called Fleetwood, they said that Ford would have installed the air bags and gave me the number to call, Ford says that Fleetwood would have installed the air bags so I should get the info from them. I gave up and have come here to ask the question. How much air psi should I put in those bags. Thanks Bill.
