I take it you didn't wait to start towing after the first 500 miles on the truck or limit your speed to 50 mph between 501 miles and 1,000 miles when towing ? :-laf
Nice truck... ... black is sweet when clean. Enjoy !

Nope, no 50MPH or mile limit here

We did alternate between 5 & 6th gear to vary the RPM's while cruising though.
MPG went up as it broke in. First 2 tanks were 8MPG. . last one was 9. 5mpg.
Haven't experienced a regen that I know of. . Almost 1300 miles on the odometer now.
