Wait 1000 miles to tow with new F150 EB?

I waited the 1000 miles as the manual says. Was actually hard to get the 1K on before our first trip 4 weeks after we purchased. All I can say is it towed great! Don't want to do anything that might void a repair. I wonder if the system remembers when you've had a trailer hooked up. It's certainly integrated into the info system.

First tow saw 9.6 on way out and 9.8 back on 500 mile trip. Flat land down I-10 to Pensacola but nice to keep it in cruise the whole way and never have crazy downshifts that I used to with my Tahoe.
