My rocking was reduced when I added a set of Hellwig Load Pro springs. This allowed me to lower the pressure in my airbags from around 50 to 20-25. A spring stack has one huge advantage over airbags in that the friction between the individual leaves of the stack means the rebound force will be less than the compression force. Airbags are good for leveling the rig but beware of high pressures as you get the bounce ball affect of a rebound that essentially equals the compression force. If I had it to do over, I'd go straight to an added spring pack (Hellwig/Supersprings) and avoid the aribags, compressor, plumbing...
I had installed a Hellwig sway bar (not Big Wig) before I picked up the camper so can't give a good before/after review on that.
