Tow haul mode?
Pulling 10,000 lb fifth wheel with f350, 6.4 deisel.. do you have to always use tow haul mode even on flat interstates?

I use it if the trans seems to be hunting to hold a gear. Or if I need the engine brake.
The torque converter locks up if over 1200 RPM. So that is not a concern. There is no difference in trans temp, if not getting a lot of shifting. If driving into a head wind, or in the hills, I use it.
Fuel mileage is better without TH.
