Air bags/bladders/etc are "helper" springs...no different than "add-a-leaf', coil, etc...suppliment to the OEM rear suspension spring system. They increase the rear axle spring rate and rate/travel curve
WD Hitch (WEIGHT DISTRIBUTION Hitch) system does NOT increase the rear spring rate....but moves the trailer TONGUE weight (distribute) from the TV rear suspension over to the TV front suspension. A percentage is distributed back onto the trailer tongue
Air bags DO NOT distribute weight...just holds up more weight. They can re-orient the attitude of the TV if the weight on the rear axle compresses the rear suspension (squat)
Think of these two as INDEPENDENT ADJUSTMENTS that interact with the TV suspension
