I had a Beaver with 8 airbags for ten years. I traded it a few years ago for an Entegra on a 4 airbag Spartan chassis. The Spartan chassis rides far better, and handles just as well or better, so I don't miss the extra airbags at all. To be fair, the Beaver was 40 feet with no tag, and the Entegra is 45 feet with a tag, so the comparison is not a direct one. But my point is that eight airbags are not needed to make an outstanding chassis. Witness all the high end Newmars, Entegras, American coaches and others on four airbags.
