Controlling Sway Stresses Trailer Frame?

Let's say I have a travel trailer with a BAD sway problem. Rather than fix the problem, I decide to "fix" the problem with a Propride or Hensley.

Even though the trailer is now "fine," underneath all that it is still TRYING to sway. The Hensley/Propride is stopping the trailer from getting out of control, but the trailer is still slamming side-to-side against the sway control.

How long before something breaks?

Sway control features are often 'band-aids' more than 'insurance' in case something goes wrong. They should not mask a known problem; the problem should be fixed and in some cases it is a problem with how the trailer is loaded and not enough tongue weight, poor design, or perhaps incompatability with the tow vehicle. In any event waiting for a part to break is not smart regardless how long or not that takes.
