Trailer ratings for 2WD auto F250 X-cab 5.8L 3.55: GCW 11,500 , GTW 6400, Trailer Frontal Area 60 sq.ft.
This implies the truck curb weight is ~5100 lbs, but the local scale says it's ~5300 with only a quarter tank of gas and a hitch receiver.
I might swap the rear diff cover to
Ford 8C3Z-4033-A or
Dorman 697-725.
Front sway bar 1"; rear 1.125"
