Towing in slick conditions

Twistedlarch, my guess is that you know ten times more than I do about this subject. But I have heard that if you have sway control, it can make things worse on ice -- it turns the tow vehicle and the trailer into a single sliding unit. So the manufacturers advise loosening the sway bar in icy weather.

Displaying my ignorance, I have no idea if the same reasoning applies to WD hitches.

Good luck!
