The OEM and other single bag systems transfers road shock from one one rear tire to the opposite tire giving a smoother ride. It also by design balances the rear load between the two wheels on each side.
The Quadra bag does not transfer the road shock of a bump to the opposite wheel... it transfers the shock directly to the bogie mount and to the frame. Look at any tandem axle, they use a pivot point between the two springs to balance the load between the wheels and to transfer shock. The quadra bag does none of this.
My current airbags are a single bag from Applied, I believe were called "Silvertone" at the time (~2010). I'm not sure if they are a current model, but I would not recommend them because if they deflate the internal opening for the inflation air gets covered by the opposite side of the airbag. This prevents you from re-inflating the airbag until you lift the coach a bit using a jack, then you can re-inflate the airbag.
When I replace them, I will go with Cinnabar reproduction OEM or the Alex Ferrara single bag.
