When I bought it (off the charity lot), it was on a flat lot and looked to be level. All Air Bags are shot, totally rotted away. I have only driven it a short distance and it seam to ride and handle OK. The RV needed some work before I can use it. I have looked at a 1986 Coachmen 30 foot and the spring looked to be the same. It too had no air bag, but I believe the Coachmen is lighter in weight. I am also needing to replace the bags. I have been looking at the Timbren SES for the rear. But I still haven't decided on air bags or the Timbren.
Thanks
