Set the shocks to 3 or 4 on the rear when empty. Rides firm and better than the stock shocks. With the stocks on the front, I could hit the bumpstops with a ride over a small speed bump at slow speed. I adjusted the front 9000s to where it doesn't hit and rides firm and comfortable. I believe they are at 4 or 5.
We just returned from a long trip with the camper. I drove to Bloomington, IN, for a conference. The wife flew out and we went to Southern Utah and canyon country for a couple weeks of recreation. Enjoyed the trip very much. Truck and camper combo with the additions of the air bags, sway bar, and shocks worked very well! Truck rode firm but comfortable. You know the load is there but not uncomfortable to drive at all. From 2-lane to super highway, I'm very pleased with the results. I think you'll like the switch.
