Just flipped through the manuals that came with my truck. There is mention of weight distribution...but no guidelines of when you'd use it -- like above a certain amount of trailer or tongue weight, type of trailer, etc. I do have the integrated Ford brake controller...which has integrated sway control. The blurb in the manual states that the sway control feature does not stop sway from happening, but that it will detect the beginning signs of sway and mitigate how much by applying brakes independently to each trailer wheel to keep it under control. Not quite sure how this plays into the overall subject...but thought it was noteworthy?
