I have four corner air bags on my W22 chassis and love them. We travel a lot in the Great Plains where high winds are pretty common, especially in the afternoon. I just pump my air bags up to 80psi or so and keep on truckin. I pass all kinds of RV's, both gas and DP's that are pulling over because they can't handle a little crosswind. Once the wind has died down, I let the pressure back down to 20psi and the ride is fine.
I guess it all depends on what you are looking for. If you want stability on the highway, my air bags work great with just a touch of the buttons on my dash to pump them up or deflate them.
