Suspension mods for 2010 Ford F450 4x4 for large camper?

I use a mix of the StableLoads and Energy Suspension stops. The ES stops are softer but allow more compression before fully engaging the overloads which makes the truck squat more. The SL stops slap my overloads on rough roadway when unloaded making the ride harsher than should be. I compromised by using the SL on the rear half of the spring and ES on the front half.
