Another reason why some people feel they have too much truck rear end sag is that their WDH is undersized for the tongue weight of the trailer. --- If this is the case, you should actually get an appropriately sized WDH or alternatively use air bags to lift the back up a little (as long as you do not exceed the rear axle weight). In this example, the WDH bears some of the load and the airbags "sort of" bear some of the load.
IMO, an "undersized" WDH means that it cannot satisfy the front axle load restoration objective.

It makes no difference if the airbags bear some of the load -- they cannot transfer load to the front axle.

Agreed, a properly sized WDH is the best way, but as long as you are not exceeding rear axle load and you want a level truck, you can do it. My opinion is that a vehicle designed to drive level will be more stable if it is level.
