Sway Problem / Need Help

I am towing a 253RB Sunset Trail(30') with a F150 Ecoboost and am having a hard time with it if there is ANY wind at all.
For the most part it tows ok on a calm day but if there is any wind at all it feels very unstable in the back end and reduce speed considerably / "white knuckling" it.
I am using a Anderson hitch which I am debating on changing out with something that can transfer the weight better. I also added a Roadmaster suspension kit to the truck to help take some of the squat out.
I used this hitch on my last Sunset trailer which was a foot bigger so figured it would be fine. (Although we never had it long so maybe just never noticed) Tow vehicle then was a 2015 F150 Ecoboost with Goodyear airbags.

Current Setup

Truck & Trailer Combined

I can't get all the sag out and am wondering if the Anderson is just too light for this setup and possibly what is causing it to feel unstable as well.

Any thoughts, hitch recommendations??

  • Tongue weight appears to be over 1000 lbs according to those numbers. That seems high if you're using a WD hitch. It's already close to the max I think that hitch can handle.
  • Ya, several thoughts:

    #1. Wind buffet and sway are tow entirely different things. Wind buffet will hit you and push you around but will end after a few cycles. Sway will start and the cycles will get worse unless action is taken.

    Which type do you have?

    #2. Out of all the figures you have you don't have THE most important. Tongue weight. Tongue weight (or lack there of) causes 95%+ of true sway issues.

    Get the actual tongue weight and get back to us.

    BTW, I have towed tons with just a ball hitch with no problems as long as the tongue weight is correct. If the tongue weight is not correct it tows like garbage.
