Is there a break in period before I can tow?
I am buying a new 2017 f250 0 miles on Friday. We leave out for a 3 hour tow 8700 lb travel trailer 6 days after that. Is there a certain mileage I should but on this before hooking and towing?

I would caution you against comparing your F250 to a class 8 rig. Compare how many quarts your diff holds to the gallons of a class 8. The ring gear alone weighs every bit of 50 lbs. The big boys are built to take some abuse.
In reality, gear mating is a relic from the past.
When machining wasn't as good as it is today, and installation wasn't either.
Installed properly, the gears will be matched with no mating needed.
Proof is in the magnant. In the past, it was common for there to be metal on it, especially at the first fluid change from the mating during break in. My last trucks, and the one I regeared myself 10 years ago have had very clean magnants.
Just as motor production has improved to the point where break in isn't needed anymore, so has the gears.
Remember the days of break in oil? It doesn't even exist anymore.
