I was afraid of that after I got home and looked online. Tomorrow, I should be able to take my truck back out there.

No, you don’t need to re-weigh anything.
You have about 1000lb tongue weight and a 5700lb trailer.
Just do the math. It’s only addition and subtraction
Looks like about perfect loading for a half ton.
Carry on and don’t make it a rvnet science project.....the geezers here will be having you add the weight of every half rack of beer you pack and deduct if you’ve had a bowel movement since weighing the last time!

Agree with grit
Total trailer is at 5700, 1000 lbs of hitch wieght. A bit over 15%,I woul like to see less. Should be max about 850-900.
I would also like to see a bit less weight transfer back to front axles. Aroun 2900 us my swag. Since you don't list base axle difference, this is hard to say. My swag is you've transfered too much wieght to FA. Could be wrong.

Looks like your a quite a bit heavy on the tongue. In my experience too much tongue weight can cause issues. I would shoot for 12% which would be 700lbs!

So it's all in his imagination then?

Yes, the tongue weight is heavy, but it's a toy hauler. The tongue weight is going to be high because everything is up front.

Now, you're never going to ever get rid of the push-pull 100%. A stiffer connection between truck and trailer will help, which means better sway control. Not sure how the Blue Ox works, but it may not be adequate in your situation. I would look into an Equal-i-zer, or a Reese Dual Cam.

FIRST thing to do is dump the soft stock tires and buy quality "E" rated tires for the truck.
This made a BIG difference for me when towing a TT. I will add once again, Timbrens helped a lot as well.

You towed to the scale and back. Did you increase tire pressure to max on all 8 tires? If so, did that make a difference?

Now I believe that I have all the proper weights:

With WDS engaged:
Front axle truck 3040
Drive axle 3080
Trailer 4760

Wthout WDS:
Front truck 2680
Drive 3540
Trailer 4640

Truckonly:
steer Axle 3020
Drive 2160

It looks like you are transferring the weight properly. I still say you need to drop approx 300lbs off the tongue.

According to a calculator I found online, my tongue weight is 18%. I think everybody agrees this is too high.

How do I bring this down?

As suggested, I increased my truck tire pressure to 50. For the short highway drive to the weight station, it seemed to help some but don't think it is the total solution.

Several have mentioned the equalizer as the best system. I might be interested in switching. My Blue Ox uses chains for connection and it is very difficult to get it as tight as the manufacturer recommends. I have to raise the hitch way high to get it latched on and off. Even at that it requires a lot of strength of which I'm not sure I will have enough of everyday.

IMHO, unless your TV's axle can NOT handle that weight, it is okay, as the range I shoot for is 15%-20%. That is the 'why' OEM's list 10% tongue weight trailers, as that keeps the TV's rear GAWR from becoming an issue

Maybe check the pointing of your trailer

It should be level at it's highest pointing and my preference is to point slightly down below level

On tires...the sidewall 'stiffness' and 'strength' is what it is all about when folks recommend going to next higher class tire...first order is whether the tires are rated for the weight carry molded into its sidewall

Lower profile "P" class helps, as there is less sidewall to flex.Going up to the next class tire, "LT", has the sidewalls designed and constructed with higher strength materials...and more of it. Why the exact same tire from the same OEM, same model, same size, etc will have the higher class tire cost more and weigh more

Wider rims (over stock) also helps, as it has less sidewall bend-back. So the sidewalls are 'straighter' and less likely to bend/fold/roll over the rim

Note that these things improves performance...but...reduces 'ride quality'. If 'ride quality' is higher than 'performance' on your 'have to have' list, then decide whether to go this route on tires or not. Trailer pointing should not affect ride quality and improves how the trailer follows the TV

Finally, if the Blue Ox (my choice and recommendation for most applications) doesn't 'center' the trailer fast enough for your tasts, consider adding a friction bar kit
