There are many here who will jump on this as well but using your hitch pin as a mounting point is NOT the same strength as using a receiver mounted shackle. The pin is designed to work in SHEAR not in bending. When the hitch is in the main forces on the pin are shear, once the receiver is removed you change these forces to bending. The pin is high strength steel but is brittle and will not take the bending moment in the same way as having a hitch installed. I have seen many people do this(without failure) but like other things you don't want to be the one to have it fail. Assuming that the hitch pin will have the same rating as a stand alone mount is a very dangerous assumption.
OP. Hitch mounted recovery points are the strongest and safest way to distribute the loads to the rear of your truck. Just get the shackle receiver mount and don't worry about it.

If you plan for every contingency, itís an activity not an adventure.
