WDH with air suspension, no standard answer?

I have an older Tahoe with the Nivomat style self-adjusting shocks that can't be disabled. When I first set it up I had to adjust it a few times to get the weight transfer right to the front wheels, but once I did it's been perfect ever since and I just hook it up and drive. It does a decent job of self-leveling, even when towing. I can tow with the passenger compartment empty or put a bunch of heavy stuff in back over the axle, and after a few miles it will pump itself up right back to level. The only weird aspect of it is that after you unhook it rides too high. If you unhook, go drive around, and then hook back up, sometimes there won't be enough throw on the tongue jack to clear the jack shoe off the ground because it has pumped itself down. I solve this by either bouncing up and down on the hitch until it pumps up, or use a block under the jack that I can skid it off of.
