Diesel break in...
Not concerned about motor. Rings will seat pretty quick in a diesel. Just a few heat cycles, 2-3. Compression is so high. Get some vacuum on it also. I would heat cycle it a bit. Will likely have ~2 heat cycles on it when you pick it up.
Gas motor needs 4-5 heat cycles on the rings. 1-2 is just drive gentle. 2-3 start to get more aggressive. Force trans into higher gear via manual shift and do some WOT pulls(not to redliine) and then let vacuum pull it back down. 4-5 get more aggressive take it to redline and then vacuum to pull it back down. If rings arent seated after ~5 heat cycles they are fucked. Was taught this by a guy who has been building engines for ~40 years.
Differential needs a few heat cycles to do some lapping. 4-5 30 mile loops, no WOT, nothing over ~55mph. Gets the gears lapped, gets them up to temp, then on the cool down the steel will absorb some oil. Was taught this by a guy who owns a shop setting gears. They set easily 3k sets of gears a year. The thing I have learned about gears is they are either noisy from the get go(shit setup) or they are good forever(or until a bearing lets go and tolerances go to shit LOL).
And LOL at Ford tracking trailer towing vs. not during break in...
I have a buddy with a big landscaping company buys a lot of trucks. Tows with them immediately. EVERY truck he has tows from day 1. Never an issue.
Go get your trailer. Work the truck a little on the 200 mile drive. Maybe drive 50 miles, stop for an hour for lunch, drive another 50, etc... but even at that, meh... dont be dumb with the trailer hooked up.
