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 miss it when I forget to turn it on. I haul 12k and it helps with higher shift points for accelerating, more aggressive downshifts for braking, all with no real impact on fuel economy. It's my buddy when I'm in the hills, both uphill and down. My engine seldom strains and my brakes seldom heat up.
