This is alot more stuck than any of you guys are probably going to get, but, this quite clearly shows why I hate pulling off of a reciever hitch:

This was after they tried winching it and were doing nothing but dragging 2 jeeps and a F150 towards the stuck jeep...
We ended up spending the next 45 minutes with my truck anchored to a tree with my winch and using his winch to slowly, very slowly pull the jeep out.
Always keep in mind that the forces involved, even in an easy no jerk pull can be extreme, and if you are questioning it being strong enough at all, make it stronger so that someone doesn't end up eating whatever that cable, chain or strap is attached to.
To me pulling off of those bumper brackets on a brick nose, while doable, and will probably work if you're only a little bit stuck, is not desirable, they are definitely not designed to have force applied to them in that manner. Pulling from that mount will put considerable bending forces on that bracket, as well as the bumper and the front of the frame. I have seen the front of the frame pretzeled on these trucks quite badly from just that type of loading. The leaf spring 4x4's are stronger than the 2wd's at the front of the frame, but, I still don't like that idea.
What I would do is build a piece of c or plate that bolted onto the frame at the holes the stock bumper bracket do, possibly running back and using the core support mount holes as well, as well as the 80-86 location in the front of the frame, attach the tow points to that, and then hang the bumper off of that new crossmember.
That way you have bolts in tension(front of the frame,) as well as shear, and it is going to be considerably stronger than just having it attached with bolts in shear alone. Also, the added crossmember will help spread the load, and stiffen up the front end of the truck's frame.
