An update from last weekends trip - handling was much improved, but still a bit loose. My wife mentioned how much I was moving the steering wheel to stay straight. So a new Bilstein Steering Dampener is on order to replace the one that the shop removed, as it was binding and causing the RV to pull to the right. (alignment was checked before we left and was spot-on) I had pumped the airbags up to 70psi, and the body roll went down a lot. It was much easier to drive. BTW - had the RV weighed and was 6150 lbs front, 12,020 lbs rear.
I also ordered a Hellwig rear swaybar. So thanks to everyone for their help and comments. Today, if I needed to drive it on a long trip I now could, but I am hopeful the addition of the steering dampener and sway bar will make it easier.
