Air bags on a Class A gasser

Short answer is yes. Longer answer is HOW MUCH and that will depend on multiple factors starting with who made the chassis. So we need to know.

I was planning on it but never got round 2 it before the Idiot Trucker totaled it

Air "bags" are springs. They will only help mildly with sway/body roll assuming your current springs can not carry the load. If your current springs are so bad that you are bouncing off the bump stops they will help a lot.

We REALLY need to wait for the OP to tell us what chassis and coach they have.

Any other facts you have on your coach would assist in getting good answers: age, miles, what else has been changed on the suspension, axle weights, etc.

Barring that, we could give 10 suggestions that don't apply to their coach for every one who guessed correctly. Could lead you in circles!

I installed air bags on the rear of my 95 F53 chassis to supplement the old tired leaf springs. To my surprise, the ride was better in the rear, with less road noise.

Yes, be specific about your motorhome.

Might be helpful to know what chassis you’re looking asking about. Ford/Chevy/Workhorse.
