What happens with the tongue weight limit when you are using a weight distributing hitch?

My Tacoma says the the tongue weight limit is 650 lbs. Does that mean that if my trailer has a tongue weight over 650 I need a wdh, or that I shouldn’t pull that trailer even with a wdh?

The function of a wdh is to take weight off the tongue, right? How would you even measure the tongue weight with the wdh in place?

WDH does NOT repeat NOT change the tongue weight. All it does is move weight from the truck rear axle to the truck front axle and trailer axles. If you look at the weights before and after of the axles the total will be the same. Therefore tongue weight hasn't changed.

Function of a WDH is NOT to take weight off the tongue, it is to move weight from the TV rear axle to the TV front axle and trailer axle.

Think of this experiment. you have a wheelbarrow loaded with stuff and you and the wheelbarrow are on a scale. You lift up on the handle does the overall weight change?? NO. the weight on the wheelbarrow front tire goes up, the weight on your feet goes up, the weight on the rear of the wheelbarrow feet goes down. Your arms are acting like the WD hitch.

My cat scale tickets show 200lbs removed from my truck and put onto the trailer axles when the spring bars are connected. So while the tongue weight itself doesn't change the apparent tongue weight that the truck feels does get moved
