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 have been using t/h since its inception. It is recommended to use it whenever you tow. In recent years it actually changes the logic in the TCM and PCM to correspond with the loads and braking. Shift points and rev limiter also are modified.
