Or you can control your trailer by driving like a normal person. Trailer sway control is completely detected by the truck not the trailer and there is not current way for this to be accomplished.

I think the easiest way which techniqually wouldnt be trailer sway control would be to make the trailer sense when it is sway and apply a tiny bit of brake pressure to one side or the other to compensate but this would be so hard to tune for each trailer and it would have to be exact pressure or it would cause even more sway in the opposite direction. THis is one of those thingthat just doesnt seem worth it when you can simply become a better driver and control your trailer yourself.
