Hi Bev,

Sorry I may have given you some mis-information. I didn't consider you might have air assist bags in your spring suspension. In this case it would probably be worthwhile to go to a public scale in your area and get your coach weighed. Ideally you would get a "four corner" weight (the weight on each wheel measured or calculated independently. At a minimum you would want to get each axle weight independently. Once you have the weights, you can adjust the air assist bag pressure according to your manual.

Four corner weights are not necessary for the pressures in the P32 air assisted front suspension, only the total weight on the front axle as loaded for travel.
The minimun is 55psi. I suggest starting at 70 psi and adjust from there until the ride and handling are the best.
Pressure changes of as little 2-3 psi can make quite a difference. Keep the pressure the equal in both bags.

Art and Bev.
Here is my advice. Check the pressure in the bags. If they are over 55 lbs adjust them to 70 lbs as a starting point. You can then adjust up or down in increments of 2-3 lbs untill the ride suits you. Do not go below 55 lbs.
If the pressure is below 55 lbs. raise the front of the coach until the front suspension is fully extended and fill the bags to 100 lbs. That will allow the bags to fully expand and bring the ride hight to normal. lower the coach and adjust the pressure to the desired level, again no lower than 55 lbs.

Keep in mind that changes to the air bag pressure( if enough to affect ride height) will change your front wheel alignment . I would recommend a reputable alignment shop set the pressure to give optimal ride height and align it at that time, then maintain that pressure.

We had our height adjusted and made a big difference in the handling.

The ride height affects camber and toe-in the most, caster (which is not a tire wearing angle) least. If the question was how to maintain the recommended pressure....
