I never said adding air bags adds weight to springs, and I understand they go between the axle and frame. I agree with you in that adding air bags and adding air to the bags will raise ride height, thereby providing some benefit of air cushioning for small road imperfections. However the single most common complaint or problem among Class A motorhomes involve sway and excessive body lean as can be verified by the thousands of posts to the thread "Cheap Handling Fix" (CHF), and dozens and dozens of other threads addressing sway and lean in motorhomes. Raising ride height higher than original design will greatly increase both sway and lean. That is why I stated the greatest benefit of just adding air bags will be achieved when you have sagged leaf springs or are loaded to capacity.
