Previous rig was a Ram 3500 Dually towing a 43' KZ Stoneridge toy hauler. I had a lot of bounce over even small bumps in the road. Finally figured out that rear suspension was almost, but not quite riding on the helper springs when static. Hit a little bump, truck squats and hits the helpers, bounce back up. Solution was to add air bags with an on board compressor. After hitching up I would inflate the bags until there was about an inch between the helper springs and their frame brackets. Compressor allowed adjustments on the fly. No more bounce.
