My '15 Chevy HD said no more than 55mph and no trailer for the first 500 miles then don't pull anything too heavy for the next 500. The differential gears are what need breaking in, the engine doesn't need it.
You should be able to find a copy of the owners manual at Ford's website, I looked up mine before I got my truck at Chevrolet's.

metalergy (sp?) has advanced so much since then that there is no longer any reason to break in engines.

I think the main reason for break in miles now is for the rear end gears to wear in a bit, not so much the engine anymore as you said. There is a lot more heat generated in rear ends when under a big load than most of us realize.

Happy Camping
My '06 GMC was 500 miles also. Rear diff break in was the reason.

Usually 500. All seals should be seated correctly by that time. It also gives the vehicle time to "learn" your driving habits.

On our new f150 the owners manual says 1000mi under the towing section, but in another place it was 500mi before pushing snow or towing over 50 miles per hour.

Here's another break-in procedure listed in my RAM owners manual that's specifically for the engine.

"While cruising, brief full-throttle acceleration within the
limits of local traffic laws, contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detrimental
and should be avoided."

What this does is help seat the rings against the cylinder walls and prevent oil pass-by. I did this a lot when the engine was new, and now at 93k miles, the engine might use 1/2 quart of oil in 5000 miles.
