Level air suspension when loaded heavy on one side.

I run a expedite single axle flatbed straight truck with air ride rear. Got a load on me going from Florida to New Jersey that is some kind of milling machine. The machine is 7 feet wide and weighs around 5 to 6k lbs. Problem is all the weight is all on the driver side. I got the machine sitting as much off center to the passenger side as I can to get the weight close to the center of the bed, but it's still not the best. My air suspension is leveling properly on the heavy side but it's causing the light side to Inflate to about 2 to 3 inches higher than normal ride height and thus cause the truck to wobble over large bumps due to the differences in bag pressure

Is there a way to drain air out of the over inflated bag to sorta level out the lean? It's drive able but looks weird and could be an easy "hey inspect me mister dot man" kind of impression. Picture is attached but looks worse than it is. Drained there air when I parked and re inflated it to take the picture. Not enough air pressure to fill the left bag but enough to fill the right lol. So in this picture the right is about 5 inches higher but y'all get the idea. I didn't feel like starting the truck just to build air

 

I like that idea of duel level valves. Might be my next little project.

Overall I just rolled with it. Wasn't that bad but if the road banked the wrong way then I'm sure it looked weird from behind. In Richmond now.
