Auto Leveling System and Weight Distribution Hitch

My Tahoe has the passive (Nivomat) auto leveling shocks. I had to re-adjust it a couple of times to get it right. I set it up initially, then drove for about 5 miles, then did it again- after the shocks pumped up there wasn't enough weight being transferred to the steer axle. Then, after really getting the trailer set up the way we camp in it, the load shifted around even more so I adjusted it a third time.
