"Twocow"....Before you throw a lot of money into this coach, you should know that particular model (R4R chassis) was rough riding and ill handling. I've never heard of rotating the axle to improve handling. I also would not want the airbags set at an angle.
The only real improvement that can be done on that coach is to.... Get the tire air pressure as low as the charts will allow for the weight. Make sure the ride height is correct, especially since they messed with the axle and add Koni shocks.
Source Engineering makes a ride enhancement kit that changes the airbags out to a larger size, changes the shocks and adds another small air tank for the bags. It's about $3K. It helps, but that chassis will still have a rough ride.
Lastly, is this your first Class A or diesel pusher? The reason I ask.....Many who drive a Class A and especially a DP for the first time, try to steer it like a car. They look right in front of the coach and try to correct the steering for every little nuance in the road. This will make it seem like it's wandering all the time. Try and look and steer toward a point farther down the road. Don't constantly correct unless you're leaving your lane.
