Ford Tow Haul Mode - Do you use it?
I previously had a 2007 F250 Diesel. It had a tow haul mode for the transmission but I only used it once because it did not seem to make much difference and caused my gas mileage to stink. I might be ...

I can only speak of the 2013 F150 and the T/H mode makes a big difference in towing... I can't say the MPG's change at all, but it drives and handles much better with it engaged..
For one thing, it attempts to keep the trans from unlocking the torque converter, which causes higher trans fluid temps.. It'll hold a lower gear "locked" longer before shifting up if you need the higher rpms to keep the TC locked.
Low rpms does not automatically equal higher mpgs... Trans life has a bit to do with things too and lugging any engine is not getting the best mpg's anyway, so why do it?
Going down hill with T/H engaged will downshift the trans if you hit the brakes too.. Yes, your rpms will rise, but you will get some additional engine braking too.. You might not know to downshift, but the computer does when you are in T/H.
But, at the end of the day, it's up to you when you engage it or not.. I don't just keep it engaged 100% of the time I'm towing.. There are times where it's not necessary, especially going down hill, but I judge that on my own..
Good luck!
