WD Hitch Weight % Transferred

Obviously, the answer to my question is going to depend, but what is a good rule of thumb to use when estimating how much weight a WD Hitch will transfer from the hitch?

Another thread recently suggested an estimate of 20-25%.

More data would help. What is the gross weight of the trailer? What tow vehicle and how many people, dogs, bbq's, firewood, bicycles, kayaks, etc do you also plan to take along? What does the truck weight empty at the scales, not brochure weights, and what is the gross weight of the truck per the manufacturer? Then we can provide more help.

Generally a WD hitch properly tensioned will place about 20-25 percent of the redistributed tongue weight back to the TT axles, the rest stays with the truck (tow vehicle plus the weight of the hitch that you might want to estimate at 100 pounds). The hitch weight plus tongue weight that remains with the tow vehicle is a direct deduct from tow vehicle payload and axle loading ratings. In most cases the front axle should be loaded to about what it was before the tongue weight was added, but not always and in some cases the manufacturers are suggesting only a fifty percent increase of the weight taken off. I know of no manufacturer that suggests adding back more weight than was taken off. The best way to determine this is to go to the scales and weigh everything and also use a tongue scale as well.

As a rule of thumb use 13 percent of the trailer's gross weight you are looking to purchase as the tongue weight. For example a 7500 pound trailer will have a tongue weight almost 1000 pounds plus about another hundred pounds for the hitch or around 1100 pounds. That is a lot of trailer weight for a tow vehicle that has 1450 pounds of total payload available. The couple hundred pounds that the WD will redistibute to the TT axles is almost a moot point. As somebody else indicated, if 200 pounds one way or the other will make or break you, then you have too much trailer.
