My relentless pursuit to cure trailer sway - the dancing TT

Just as a question, does your Weight Distribution hitch have anti-sway bars on it? If not, try installing a set and see what happens. Your truck may cary the weight, but the trailer will sway without the anti-sway bars. I know this is a problem becase I have pulled trailers in the past with no anti-sway ars and they danced around something terrible; I put on an EqualiZer hitch and that cured the whole problem.
