Weight Distribution and Sway Control for a 2012 Ford F-150 Supercrew and Jayco Jay Flight


I recently purchased a 2012 Ford F150 Supercrew with max trailer tow package which offers a towing capacity of 11,200 lbs. We also purchased a Jayco Jay Flight, model 32TSBH travel trailer with the following specifications Unloaded Vehicle Weight 8,075 lbs, Dry Hitch Weight 940 lbs, Gross Vehicle Weight Rating 10,500 lbs and Cargo Carrying Capacity 2,425 lbs. Were interested in a weight distribution system with sway control possibly. After researching the information, we believe that the Strait-Line Weight Distribution System w Sway Control - Trunnion Bar - 12,000 lbs GTW, 1,200 lbs TW Code RP66084 is our best option. Can you please confirm that this correct? Secondly, the F150 comes with trailer sway control so Im wondering whether we should indeed get the weight distribution system with the dual cam sway control or whether we can do without the dual cam sway control. Is there an added benefit to having the sway control included with the weight distribution system or will it interfere with the sway control system that comes with the F150 truck. Lastly, I consider myself a fairly handy individual so I was wondering if you would recommend that I install the weight distribution system myself. The main benefit that I see in installing it mayself is that it will allow me to learn more about the systme and connectivity to the trailer and truck.

When choosing a weight distribution system, you need to go by the tongue weight of the trailer when loaded and ready to tow plus the weight of anything loaded behind the rear axle of the tow vehicle. If you have the trailer at the max of 10,500 pounds and tongue weight is 1,050 to 1,575 (10 to 15 percent of gross trailer weight), that will tell you what weight range you will need in a weight distribution system.

The 750 to 1,000 pound system that you referenced would not have a high enough capacity for this application. You are sort of in between sizes so if the trailer will not reach its max gross then a 600 to 1,200 pound system, like # RP66084, would be ideal.

If you will be towing at the max and have items behind the rear axle of the truck then a heavier system will be needed like # RP66130 with shank # RP54970. For either system you will need a properly sized ball like # 19286 for a 2-5/16 inch diameter for the first system, or # 63840 for the second system.

The Strait-Line systems work very well and I do recommend them because of the dual-cam sway control which proactively and aggressively resist the start of sway by forcing the vehicle and trailer to ride in straight line. And, you will not have to remove the sway control to back up or in inclement weather.

The type of sway control on the truck works differently to correct trailer sway. It adjusts power to each wheel accordingly during a swaying event. The two systems should not interfere with each other because the dual-cam systems will prevent the start of sway before the system on the truck even has to engage.

The sway control on the trailer is more ideal because it stops the sway at the source before it affects the truck. If you just used the sway control system on the truck it would not engage until the trailer started to sway and you would definitely notice the difference in ride.

A fairly handy person like you should be able to install the system without much trouble. I have included some instruction links, a video showing a typical installation, and an FAQ article for you.
