Okay, I am posting an update to my previous post in this thread. So I towed the boat up this morning instead of yesterday afternoon as I had originally planned to do. I was towing into a 25-30mph headwind the whole way. I was getting 17.5mpg until I went into an active DPF regen and then dropped to 16mpg for the rest of the trip. I would imagine with my old 2010 F150 KR 5.4 would have been getting 11mpg +/- because of the strong headwind.
As far as the active DPF regen went...much different behavior towing vs non-towing. Non-towing usually drops 5% every 1-1.5 miles until it gets down to 0% after ~19 miles of driving. Towing was dropping 5% every 10-15 miles driven--the regen kicked in I'm guessing at 85% Full, and normally in the distance I drove would have been to 0% without towing but instead only got down to 60% with towing. Once I dropped off the boat and after driving for a while the active regen resumed and cleaned out the DPF down to 0% Full at the expected decrement pace.
As far as the towing experience itself...because of the headwind I kept my speed at 60mph in the 70mph zone and my RPM's were ~1,400 in 10th gear @ 60mph towing ~4,000 pounds. (Note: my truck has 3.55 rear axle ratio). One thing I found interesting was pulling away from a dead stop--the RPM's jumped in the 2,000-3,000 range and the truck used the lower gears longer to get the load moving (was in Tow Haul Drive Mode), this is a different driving experience than what I had with my 2010 that would not have rev'd the RPM's to get the load moving. I am thinking there probably is a tuner to bring some of that torque/hp down into the lower RPM's range, as I know the peak torque in the curve is ~1,750 RPM's, but I think Ford has us tuned for efficiency down the highway once we get the load up to full speed motion.
So there you have it, my report on my first towing experience. Overall very pleased with the towing mpg and without the headwind on a long fairly level highway run it appears I will be getting ~16-17mpg (driving 70mph instead of 60mph) which is one of the main reasons I bought this baby Power Stroke over the Coyote or the EcoBust with either of them likely getting ~5mpg less towing compared to our diesels--actually, overall I am feeling like I am getting +4-5mpg's with the 3.0 over the 5.0 or 3.5 engine options in any driving conditions (again, pro's for our new F150 diesel).
