A properly loaded trailer shouldn't sway but there are environmental factors that could cause it such as draft from semis, clipping the shoulder, emergency manoeuver etc. Only takes once to wish you had it. Pretty cheap insurance for an expensive truck and trailer if you ask me.
Assuming that a Sway Bar system is any kind of "insurance" against any kind of mishap is pure folly.
If you dont know how to handle that trailer or have the right instincts already when something dire happens then no sway bar system is going to save you. Your fate is in YOUR hands and in your head not in two metal bars on your trailer tongue.
The fact is "sway" is in the mind of the driver. Drafts from Semis dont cause sway. Hundreds of semis have passed me both ways on four and two lane roads and never once have I experienced any trace of what you would call sway.
This entire sway issue is really one of education: Learning to drive your trailer and learning to load it correctly.
