Help with hitch / tongue weight

Tongue weight is typically defined as the static force the trailer tongue exerts on the hitch ball. Setting up the WD system, to distribute the tongue weight AND the cargo in the bed that you typically haul is obviously the best setup. But, that doesn't mean that the weight you add to the bed, even if it is behind the axles, is tongue weight. What you are distributing is tongue weight AND the cargo weight that is behind the rear axle. None of the added cargo is tongue weight, but it can be part of what needs to be distributed.
