More suspension help!

We have an Arctic Fox 1150 on a F350 dually diesel 2WD with the heaviest spring pack Ford offers. I have Rancho 9000shocks and air bags with on-board compressor and separate adjustability, when fully loaded (including 47 gallons of water) I run 40 psig in the air bags. I put on Timbrens for on year, not that they were needed but wanted a softer axle stop on large bumps as the factory bump stops are quite hard, but the 1150 is a heavy camper and the center of gravity is behind the rear axle so the truck's nose would bounce up and down a lot, so took them off. We are on our sixth year with this rig and have no complaints. Good luck and Happy Camping!
