I tend to agree with the WD option, the purpose of WD is to restore FA weight, weight equals sag, the restoration of which eliminates the 'sag'.

The wheelbase on my truck is 13'; the hitch is 4.5' behind the rear axle.
Say I wanted to move the effective tongue weight to be in the center of the vehicle. I'd need to apply (6.5 + 4.5) * 500 or 5500 ft-lbs of torque. If I'm carrying more weight in the bed, I'd have to crank it up more to level the truck. I'm way better off just leveling the truck w/ the air bags. I'm well within both rear and front axle loadings - this is purely a matter of ride attitude. It is much easier to adjust the air pressure than to fiddle with WD hitches.
