Air bag suspension for trucks question

I can tell you I had airbags on my 2007 Cambria Class C. It made all the difference in the world when they were inflated properly. Proper inflation depends on how much weight is involved. With out the Air bags the rig was a bad handler. With 55 psi it handled like a dream. Those that say you cannot use them to increase your weight are correct. However, they make a hell of difference in how well that weight is handled.
