Tow haul and overdrive
Does tow haul lock out overdrive? Mine doesn't seem to or, I haven't observed correctly.

No, tow/haul does not lock out overdrive on any GM or Ram truck, at least. Tow/haul only changes your shift points on the transmission.
If your truck normally shifts into overdrive at, lets say 55 MPH, in tow/haul mode you may need to hit 60-65 before it shifts into overdrive.
Same for Ford. At least for the last 10 yrs or more.
