"SeVeReDiStOrTiOn" had it exactly correct.
This is directly from my 06 manual:
"TOW HAUL” mode, 5th gear (if equipped) is disabled
and 2-3 and 3-4 shift patterns are modified. Shifts into
Overdrive (4th gear) are allowed during steady cruise
(for improved fuel economy) and automatic closed throttle
downshifts to 3rd gear are performed (for improved
braking) when driving conditions warrant. Pressing
the “TOW HAUL O/D OFF” button a second time to
select O/D OFF will disable 4th and 5th gear completely,
which should eliminate any excessive transmission shifting."

That is correct. My 08 works just as the manual states.
Tow/Haul = higher shift points at part throttle 2-3 and 3-4 with 5th locked out at any speed.
OD OFF = No 4th or 5th gear at any speed.
