Air Shocks
What about air shocks on a towing rig. Anyone use these instead of air bags? Or is that to much pressure on the shock mounts?

Just for grins, an example would be a trailer with 1000lbs of tongue weight. You adjust the WDH to put about 500lbs on both the front and rear axle. Add some cargo in the bed. That might put the front down 1/2" and the rear down several inches. Do you really want to drive with the headlights blinding oncoming traffic?
If a trailer-induced load of 750# plus "some cargo" in the bed causes the rear to drop "several inches" the TV's rear axle probably is overloaded.
As APT posted, a properly adjusted WDH might result in a rear-end sag of about 1.5-2". It's very unusual to hear of more than 2" sag with a properly adjusted WDH. From the reports I've read, 1" is more common than 2".

If the load change were "approximately zero" then where did the weight distribute to?
I understand that one wouldn't want to transfer fully 1/2 the weight to the front, I was trying to show that front and rear spring rates may be quite different causing the rear sag problem on some trucks.
Just Google F250 rear sag and read.
