Yes, when adjusted correctly. The air bags simply support the weight that is over the TV's rear axle, possibly minimize rear TV squat when under load, but they don't have any weight distribution function.
The WDH's main function is to return the same weight that was removed from the TV's front axle do to the effect of the tongue weight placed on the hitch ball (front of TV rises, rear of TV squats). By returning the TV's front suspension back to it's original condition re-establishes normal steering and handling characteristics.
If a TT's loaded tongue weight falls within the TV's "weight carrying" mode limits, the TV manufacture is basically saying that the front suspension will remain within established tolerance limits thus a WDH isn't required. It should be noted that any added cargo placed within the TV located behind
the TV rear axle should be counted against the specified "weight carrying" mode limit just to be on the safe side.
The WDH will reduce TV/TT bounce thus aiding in maintaining proper TV steering and handling characteristics.
Travel safe, camping season is just around the corner
