I'm sure glad you never got a chance to talk to the full trailer I pulled the most. MT TW was less than 0.05%. Loaded, less than 0.005%. Replace bushings in tongue about every 50,000 miles, and it tracked like it was on rails.
Now when talking RVs, or most other trailers, the TW is important. You should set things up to where sway is unlikely, then add sway control for when something goes wrong.
So What you're saying is the dump pup or transfer you pulled didn't have any tongue weight, per se. This is not news, nor in any way pertinent to the discussion.
All it has to do with this discussion is to point out anybody claiming "all trailers must have TW" might not have all the info. Sometimes something like just changing tire size, air pressure, or height of hitch can make a well behaved trailer sway. And a change in overhang/wheelbase ratio can change mean that sway that is unnoticeable behind 1 TV can't be towed by another.

There is a reason they call those "Wiggle Wagons".
Sorry, never heard a rigid framed pup trailer called Wiggle Wagon. With about 10 foot wheelbase, tires had to slip sideways to turn much. Kinda like a toad behind a MH, except the steering is locked straight ahead. (How much do they sway?)
Wiggle Wagon is normally a semi-trailer with converter in place of tractor, (Some trailers are built so the front axle can spin under like a converter) This gives a extra pivot point behind the truck, (more often another semi-trailer) Now they can, and often do wander around behind. But unlike true trailer sway, all forces on the TV are straight back, not pushing side to side. Really not a control issue unless driver tries to correct for it, oversteers.
