On my old Super Duty pickups it was tow/ haul a__ mode--made them really zippy for an 8000lb truck in tow/haul mode.

I think you are half right: Tow/haul does hold the lower gears longer on acceleration but it delays downshifting when going up grades so you don't cycle the transmission in hilly areas unless needed.
I stay in normal when ramping onto an Interstate and then shift to tow/haul when I am up to speed if I am not towing. I use it all the time if I am towing.
