Minor sway issue

I received an email response from Sean at ProPride. Here it is

"Removing too much weigh off the rear axle of the tow vehicle by raising the weight distribution jacks too much can certainly throw some movement into the hitch and then the trailer. The hitch will only move from the tow vehicle side so if the rear end is light it could have been drifting a little at higher speeds."

Rob, in a previous post, you stated:

"---When I crank up the weight distribution as far as I can, I can't get the truck back to where it was before hooking up. I can get the front within 1/2" of where it was originally and the rear of the truck to 3/4" of where it was originally but that's all.---"

On your recent trip, do you think you were able to crank up the weight distribution enough to restore the front axle load to its unhitched value?
Even if you were able to achieve 100% front axle load restoration, your 1100# tongue weight still would be causing a load of around 800# to be added to the rear axle of your 2500HD.

Have you ever noted any tendency for the rear of the truck to "drift" when not towing?
If it doesn't "drift" when not towing, I'm wondering what might be causing it to do so when you are towing with an additional load of 800# or more on the rear axle.

Removing too much weight off the rear axle would be accompanied by adding to much weight to the front axle -- both of which could cause an "oversteer" condition.
During those periods when the rear of the trailer was swaying back and forth about 3 inches, did you notice any increased sensitivity to steering inputs?

If you are able to reproduce the TV and TT loading with the WDH adjusted as it was when you were experiencing the swaying, it would be very informative to measure the hitched and unhitched axle loads under those conditions.
