Just don't work it hard and you will be fine.
Ford recommends 500 miles.
I had to go to work the next morning towing my mini excavator and skid loader after I bought mine. So I went for a drive that night and put 100 miles on mine. I mean that is only 2 hours of driving and it gave me a chance to play with all the controls.
But if you are on flat land, can do easy towing, I wouldn't feel bad about towing right away. Just be easy on the rig starting and stopping and avoid steep grades. I wouldn't go blasting up a 12% grade at full rpm with 15,000lbs at 25 miles on the Odo.
Just think how many commercial companies buy a new truck and it goes directly to work tomorrow, Ambulances, trucks with dumps beds or heavy tool beds etc.
Probably more important is to vary your speed and work load of the truck for that first 500 miles. Don't just hook up and head out on the freeway with the cruise set at 70mph
Ford says these new engines do not need a special break in. So the recommendation is for rear end, transmission and other components as much as getting the engine some mileage.
