Hi John,
I use the wireless air controller in both our coaches. That manifold is factory set to max of 100 psi and cannot be changed. That was not enough to attain max height with the stock one air bag system so I added air bag risers to both coaches. Without the air bag risers it took over 90 psi to achieve proper ride height on the Royale with four 6vdc golf cat batteries in the rear compartment where the propane tank is in the GMC models. On the Royale, the propane tank is under the dinette so that rear compartment is open. It took a bit less pressure to get the Clasco up to proper ride height as it has only one 4d AGM battery beside the generator so less extended weight. With the air bag risers in place the Royale reaches proper ride height at 75 psi and the Clasco 65-70. In both cases there is 25 or more PSI to raise for leveling and that seems to max out the rear shock limits. Each combination of rear air bag configuration and effective working height of the bag relative
to the pivot point on the bogie arm will take a different amount of air pressure to raise the coach to the shock limits so no one answer will fit all circumstances.

Hi All. I know that some of you have air pressure gauges conected to each air bag on your coach. I know it will be dependent on coach gross weight,
but what pressure are you noting as being needed to raise the coach to the shock limits. (Max height During camping).
