When in the south I am comfortable at 55-60 psi. When in the north it is more 40-45psi. Road condition dictates. Just drove from WI to Michigan and back via the UP and set them at 50 psi to start and reduced to 40 psi on the return. Ride was pretty good over some poor roads.

I have the system installed on mine, front and rear both. I usually run from 60-70 psi in the fronts, but it depends on how I am loaded, number of passengers, towing, etc. I can say that you should try adjusting to lower or higher pressures until you find where your rig rides and handles the best at. I believe that Kelderman recommends a generic or close to figure of the air pressure, but each rig is different and you need to find the psi that works best for you. Just be careful not to exceed the max high pressure rating for the air bag. Hopefully this is helpful to you. I love mine, night and day difference in the ride and handling both.
