Use WD hitch or not?

Trailer chassis all correct.
Experiment with different WD settings.

Yeah, it's all new. The tires probably could be upgraded to a LT, and I might go with a smaller diameter to get a stiffer sidewall (it's geared quite high so it wouldn't hurt). They are at max pressure for the tire, 44 psi.

I had an old Passat that I wanted to gear up so I got the next size taller tire that would fit in the wheel well. That worked well so I went another increment up on my next set of tires. That made for a less controlled ride than before. I think you can go too far in the tall tire direction. The tires on this truck are pretty tall.

I guess the trailer chassis is correct. It's new too. The tires are nothing special, some H118 brand or something like that. Might not hurt to go with a better set there too (it's tandem axle). Max pressure is 50 and I currently have them at 45. I know, everybody says go to max; just haven't gotten around to it.
I could crank on the WD bars a little more too. The front doesn't move but it could go down a bit as the rear goes down quite a bit.

Paul, for what it's worth, when I got my camper (4000 pound, tandem axle ) it came with load range C ST tires (50psi). I used them for a while, then replaced them with load range D LT tires. I run these LRD tires at 65 psi, and it is a very much improved towing trailer just from that tire and pressure change alone.
And yes, in your case, I'd scale it at the CAT scale, and get front back to exactly what it weighs unloaded, and see how that goes.
