payload and WD hitch clarification

[fourboysdad]

With four sons and a wife in a Nissan Armada with 1450 payload, tongue weight becomes a factor pretty quick. We're in the market for a camper that'll sleep all of us.

What I believe I understand: when a WD hitch is engaged, it will distribute the hitch load to the front, rear, and trailer axles. That I get.

What I think is right: when a WD hitch is engaged, a percentage of the hitch load is redirected to the trailer axles and off of the truck frame.

I'm concerned about payload. Assume I have 675lbs reserved for hitch load. If I were to get a camper that has an 700lb hitch load, would I be correct that if my WD hitch is set up right, that a percentage of that 700lb hitch load would be put back on the trailer axles and not on the truck frame thus keeping the truck from being overloaded? I can't seem to connect these dots.

My family is too valuable to me to overload the truck. Thoughts? Thanks!

The problem here is that if you are that close to have to be figuring if the small amount of dead tongue wt. being transferred back to the trailer axles when the WDH is hook up tells me you're too close to begin with. This is because you have absolutely no idea what the dead tongue wt. will ACTUALLY BE and typically the percent of dead tongue wt. (i.e. the wt. of the trailer tongue independently measured by a scale) is only in the 10 to 25% range so at 700 lbs that is only 70 to 175 lbs and if your cutting things that close IMO you don't have enough reserve to be safe and comfortable.

FYI the listed tonue weight on most trailers is "dry weight" and it does not include the weight of items on the tongue such as propane in the tanks (typical 20# per bottle) battery(s) (typical 50# each). It does not include the hitch receiver on the truck (50 to 100#) nor anything you add into the trailer - clothes, food, water, etc all of which will add to the tongue weight.

It would be a good idea to load up the truck with you family and get the truck weighed and subtract that from the GVWR to get how much you have left for the LOADED tongue weight.

Biscuit - Thanks, I've read over that several times prior to my post, and I guess I'm just looking for confirmation that my understanding is correct. There's enough information on here to get lost if you're not careful. Thanks!
