This decision is still open. 3 options are being compared, nothing has been ordered, and no manufacturer has been committed to. Where one option is marked as currently leaning, that's a preference at this stage — not a decision.
1 in adjustable rear sway bar
Currently leaning
Hellwig
Researching
Current preference — no decision made
Part number: 7788
Why this option
Adjustable so roll stiffness can be tuned once the Airstream is actually behind the truck, rather than committed to a fixed rate on paper. Reduces body roll under trailer load without touching ride height or spring rate.

Active Suspension system
Roadmaster
Researching
Why this option
Addresses trailer-induced sway from a different direction, adding progressive spring assistance rather than roll stiffness.
Where it currently stands
Overlaps with what the Timbren kit is already doing for load support. Adding roll stiffness and progressive springing to the same axle risks over-correcting the rear.

Retain factory rear setup
Ford (OEM)
Researching
Why this option
No cost, no added weight, no change to a suspension Ford already validated for this truck's tow rating.
Where it currently stands
Body roll under a 6,500 lb trailer is the specific complaint being solved. Leaving it stock means accepting it.
