After reading the more detailed towing guide per Bills suggestion, I think I'm a little bit clearer as to the capabilities.

Summary of what I found:
HD Towing comes with everything listed in that column with X or Std.
The hitch can handle 6600# and 660# tongue with weight carrying, and the full 9200# with 920# tongue with ONLY a WDH.

It seems as though you will void your warranty if you tow over 6600# without the HD Tow package even if you use a WDH. That doesn't mean the vehicle can't do it, as nothing else in the HD Tow package adds any power to the vehicle, it just all just extra cooling (bigger radiator and aux trans oil cooler).

So back to my original question. Seeing as we will be buying used (may not have any warranty remaining), how much extra benefit will we get from the extras included in the HD towing package if we will only be towing our 2720?
