I know a member here (Eric the Oracle) pulls his NX6010 Cab HST with all features, loaded tires, and brushhog with his F150 up and down MN, I think the total is about 10,000lbs. Unless your 250 has major problems, I wouldn't worry about it. I wouldn't hesitate to haul it with my suburban, which I believe has less capacity then your truck.
On slopes it downshifts to 5th, on hills it downshifts to 4th gear.
