We recently upgraded our tow vehicle, so now the hitch and ball sit much higher than the coupler on the tongue of the trailer (when its level). After hooking it up and putting all the trailer weight on the tow vehicle, and not the jack, the rear end sags. We have a weight distribution hitch, but that doesn't seem to help. What could cause this, and how do we fix it?
Thanks-

A WDH is not a one size fits all item. It is adjusted to match your specific TT to your specific TV. When you change either, the hitch has to be readjusted for the new combination.

Also a WDH can only do so much. What’s the tow vehicle and payload, and what’s the trailer and it’s tongue weight??

You upgraded to a vehicle that sits higher but has a softer suspension, presuming what you had before “worked.”
And somehow your wdh doesn’t take enough weight off the back of the vehicle to get the @ss end up.
Options: Not necessarily in order.
Crank up wdh
Upgrade rear suspension
Upgrade wdh
Get vehicle with heavier suspension.
Reduce trailer tongue weight by way of shifting trailer weight or getting a lighter trailer.

Thanks- First off, you want to change your WDHitch configuration so its ball sits at the proper level (when unhooked), same height as the trailer tongue when level. Does it have a row of bolt holes that will let you lower the head with the ball?
What brand WD hitch are you using? Different ones have different instructions for proper setup. A measuring tape might be needed.

The purpose of a WDH is to transfer some of the tongue weight to the front axle, if you have the proper amount transferred and the sag is still too great, then you need stronger springs.

It doesn't matter if the rear end sags. What matters is the trailer is level and you have transferred the recommended amount of weight back to the front axle of the truck.

It might...the trailer AND the truck are supposed to be level, and the OP hasn't given us enough info to determine what they mean by "sag".
Most trucks are designed with a forward rake, so that when unloaded the rear sits higher than the front, and when loaded the truck sits level. If that is what the OP is calling "sag" then it's fine and normal. However, if when loaded the rear of the truck sits lower than the front, that is NOT OK and means that the headlights will be scanning the trees for birds when driving at night.
The weight distributing (WD) hitch should be adjusted so that both the truck and trailer lit level, unless the trailer is beyond the ratings of either the hitch or the truck.
