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 wrong, but I think the tow haul mode would disable overdrive which is probably why my gas mileage stunk.

I now have a 2015 F150 and did some towing today with and without the tow haul mode on. In my F150 it seems to make a bigger difference. When tow haul mode was off I felt like the transmission was shifting way too often. With tow haul mode turned on the transmission shifted less often and seemed to drive better.

I guess I will just drive with the tow haul mode turned on but I was wondering what others do? Do you use it on your F150? Does it make the gas mileage a lot worse?

I have an 04 f350. Tow Haul doesn't disable 5th gear overdrive but you do have to get up to 63 or so to shift into fifth. It will then cruise in 5th at 60 or even slower. Need it there for compression breaking on downhill slopes.
