Follow the good logical advice others have given you.
Skip the sea stories by posters (someone passed me doing 85mph).
Gee Whiz stuff isn't going to solve your problem..:S
Start by dealing with "what you have".
*NOT* with what would/could/should be better.
Save that for "Round Two, Plan B" - or whatever you want to call it.
You may have to do that - but what you have *now* - is what you have.
There's obviously something amiss - or you wouldn't have posted.
For openers, tire pressure at the max pressure indicated on the sidewall of the tire.
(*IGNORE* the Goodyear "plus ten psi" recommendation.)
Determine the pin weight - by methods indicated.
Then determine if the trailer is level, and if not - work on getting it level......then repeat checking the pin weight.
One of the major advantages of a 5th over TTs is the lack of sway.
If you are encountering sway - without heavy crosswinds - there *IS* something wrong.
Almost everyone has gone over the "magic" 65mph - either accidentally or intentionally - without sway.
For those folks - guess your problem would be there at 66mph, and gone at 65mph = double duh..:R
