Friction sway to Blue Ox sway Pro

I'd have to agree with Terryallan - a properly loaded trailer shouldn't sway under normal circumstances even without the benefit of sway control ... if it does, correct that first. Start by weighing the trailer as it would normally be for camping, measure it's gross tongue weight, and ensure you're somewhere in the 13% - 14% range. Assuming your satisfied with ALL the other aspects of your towing setup - e.g. TV suspension, tires, etc - only then should you be considering upgrading your WD system. I too had planned to tow my latest trailer with a Blue Ox Sway Pro but at the time of purchase I was gifted a simple trunnion bar Reese WD system and for this size of trailer it works just fine, even without an additional sway bar. Granted, it's a much shorter, lighter trailer and had it been larger I would certainly have gone ahead with the Sway Pro BUT only after I had set the trailer up correctly so it wouldn't sway in the first place under normal conditions.
