Traction control systems and trailer sway bars

Why do you need it? If the answer is because your trailer tows poorly and is all over the road, then absolutely you cannot get rid of it. Why would you want your vehicle trying to compensate for a schitty handling trailer with its own brakes ALL the time?

However, if the answer is you do not know why you need it, perhaps only because someone said it was required, then you most likely dont need it nor did you ever need it, regardless of what fancy features the truck has.
