Rexlion I always thought the hitch weight would come off of your payload not the TW. I've never read or heard anyone reference adding the weight of the hitch to the tongue weight, but have always heard to subtract it from the payload.
Most WD hitches are easily 100lbs which would drastically impact the tongue load ratings for most TV's. I see how it could add to the tongue weight but isn't the WD hitch system designed to transfer part of that tongue load to the rear and front axles and negate that weight?
I just bought a Sherline TW scale and I didn't see anywhere in the instructions where you add the hitch weight to that scale reading. I really hope I'm correct in this otherwise I would assume most of us 1/2 ton guys could be pushing the limits.
