I think the problems people have with fifth-wheels are typically due to height: big conventional fifth-wheels are very tall, substantially taller than conventional trailers of the same size. Of course, this is to some extent a problem for an Escape 5.0 or 5.0TA as well, as they are taller than the conventional Escape models to provide enough vertical space in the sleeping loft. Pitch oscillations ("porpoising") may suggest a height issue. It's not obvious to me how high hitch weight would help this, but perhaps getting some load off of the crude trailer suspension and on to the truck's suspension helps, if only due to the truck suspension's much better damping.

Another pair of related problems are trailer length and weight - the length of the bodies of the smallest conventional fifth-wheels are almost as long as the bodies of the longest conventional travel trailers (although "park models" can be longer). They typically weigh about twice as much as the tug. I'm sure that there are stability issues with fifth-wheels, but the biggest conventional trailers are serious challenges.

Given the content of posts in that discussion, it is clearly not the place to go for any useful information. It starts with a semi truck driver who doesn't know what "semi" means...

I would not add to much weight to the rear or you may get a rig that will have a tendency to poripose.
suggests to me that the problem in some cases may be poor load distribution, with too much mass at the ends, increasing inertia about the horizontal lateral axis. This is the same problem that causes sway problems, around the vertical axis.

While an Escape 5.0TA is typically towed by a tug which doesn't weigh much more than the trailer, large conventional fifth-wheels routinely weigh more than twice as much as the tug.
I agree that the same principles apply... so I'm sure that a pile of cargo on a 5.0TA's rear bumper to counteract a heavily loaded front end is a bad plan.

My guess is that the 5.0 TA will tow better with 16% or more of the weight on the pin, assuming you don’t surpass the GVWR of the truck. But because the trailer isn’t much heavier than the tow vehicle, the improvements won’t be as noticeable as they would be with a conventional trailer.

Someone with a 5.0 TA might want to experiment with different pin weight percentages to see if they notice a difference. Maybe take a trip at 11%. Then move some weight forward to get 18% to if the difference is noticeable.

Other then water how does one move a lot of weight from one end to the other? All we have in the loft is clothes, the mattress, and maybe 30 lbs in the front storage. Maybe with cinder blocks or some such for test purposes, but realistically I can't do it real world traveling.

I agree - without a lot of enclosed storage volume in the front, people are unlikely to have lot of stuff in each end to rearrange. I think the biggest difference between people's trailers are the mass of stuff under the seats in the rear, and the amount of stuff outside on the back. I would certainly not suggest adding anything back there, but I think that's how some people cause problems.

If fitting the trailer within the pin weight capacity of a Colorado/Canyon requires shifting a lot of load, that's a problem.

An extended pin box can be used, but that will only reduce load on the hitch by a few percent (and it will likely increase air drag).
