I had a 96 motor home on a 95 P30/32 chassis. The vehicle owners manual described how to set the pressure in the airbags. In case you don't have the manual this is what mine said:

The owner’s manual gives the following ranges:

4,300 LB front suspensions = 10 psi to 50 psi
5,000 LB front suspensions = 40 psi to 50 psi
5,300 LB front suspensions = 50 psi to 80 psi
5,500 LB front suspensions = 60 psi to 100 psi

For the proper adjustment it says to inflate the air bags to the maximum pressure for your vehicle, load the motor home, park on a level surface and then reduce the air pressure as needed to level the motor home but don’t reduce it below the minimum.

I have seen other schemes for adjusting the pressure per ride quality, but the 1995 Chevrolet Forward Control Chassis owner’s manual said to do it as shown above.

I don't know if it's accurate or not but other posts have said the pressure in the bags affects the alignment and you should have it checked when you get the pressure set. The manual did not mention that however.

I think you are also suppose to raise the front wheels off the ground and deflate the bags. Then inflate to 100psi and lower wheels back on the ground. Then adjust the pressure by deflating to your desired pressure.

Be aware that no air in the bags or too little also affects the front end alignment. Ask me how I know.

I found yesterday morning, leaving today, a leaking air bag.
I did something I never like to do. I used some slime in the air bag. It was leaking between the metal insert and the bag. It is holding air. I will be doing something when we return. I may get variable rate from springs from Henderson Alighnment.
Pressure, I run 80 pounds. This is based on actual weight of front end.

I could be wrong ,but I believe the Airbags were an optional item. 50 PSI seems like too much air pressure I would have thought 10 to 15 PSI !

I think every P30 came with air bags in the coils. 10-15 lbs in the bags are way to low. From the chassis manual Air Bags Front:
For a 4,300-lb suspension, 40-50 PSI. For a 5,000-lb suspension, 50 PSI. For a 5,300-lb suspension, 70 PSI. For a 5,500-lb suspension, 90 PSI.
The GM part number is 367762 for the bags used in the 4,300 and 5,000-lb suspensions.
The GM part number is 15631881 for the bags used in the 5,300 and 5,500-lb suspensions. This is an Airlift H.D. Bag. The part numbers can be updated at any time, and a new part number of 15731951 was released for 1984 through 1997, but your handy GM dealer should be able to figure it out. Be aware that these front air bags are contributors to the GAWR (Gross Axle Weight Rating) for the chassis. Underinflation actually will decrease the rating and will undoubtedly affect handling. Overinflation makes the ride harder and doesn't increase the rating.

To get rid of the bags forever and never worry about them again go with a pair of These
