I mounted the top brackets on the frame as high as I could and used a 1" spacer at the front of the bottom bracket and none at the rear. With 5 pounds of air unloaded, I loaded my 3500 pound Lance and the truck stayed level! I haven't found my pressure guage, so I don't know what the bag pressure is with camper loaded. But it SURE makes a difference! Now I need some Bilsteins or KYB's and I'll be set!
