I've wondered if adding a small (1/4" - 3/8") anti sway bar to the
trailer axle would help in most situations. Granted, proper weight is
best, but the anti sway bar may widen the margin. Thoughts?

It's unlikely it will change the dynamics of a single axle trailer.
Ante-sway bars are used on cars and similar to change the roll stiffness
about each axle: generally, an anti-sway bar on the front axle increases
"understeer" and makes the vehicle more stable. A rear bar does the
opposite.

The place to change anti-sway bars is on the tow vehicle. I suspect a
bigger front bar would increase the towing stability, but I think it's
better to get the trailer balance and tire pressures right (ditto for
the tow vehicles tire pressures).
