WD Hitch or not?
#11
The electronic trailer sway control on a newer Ford works pretty good, but it is not a replacement for the positive mechanical sway control of a good weight-distributing hitch. Use both. If the sway control light on the dash ever lights up, that means either you don't have your hitch properly adjusted or you're not using a good WD hitch. Good WD hitches include the Blue Ox SwayPro or Equal-I-Zer or Reese Strait-Line or the original Husky CenterLine.
I do find my 28' 11" Car Hauler that weighs 3600 lb with a 360 lb tongue pulls just fine empty with out the EQ 1000 I use loaded. I can't get lighter bars for the hitch and its way to much empty.
I'm hesitant to make a suggestion to the OP because every setup is different.
