Planning on another week of sitting in the mud?
I would get all your tools lined up beforehand.
You may be able to walk on a sheet or two of plywood. Perhaps attach some rings or something so you can pull them back out. It will make climbing around the wreck more pleasant.
If you buy a winch from HF, go oversized. The 12K winches are $299 if you can find the right coupon. Or, browse Craigslist for a good Warn winch.
Assuming that is your property, and you need a trail around it, cut a new one. But with hand held equipment (come-a-longs, chainsaw winches, etc), you should still be able to crawl behind it and attach the winch to something solid behind the Ranger. Perhaps a good heavy duty pulley (I suppose I should track one down someday).
I'm trying to think of how one might build an A-Frame. You could cut wood down there to build it, then tie or chain it together. Plan on it sinking a bit, and perhaps needing winching back out, unless you can tie trees on both sides of the trail together over the rig. Anyway, If you could get about 2 feet of vertical lift, you could get some good plywood under the tires and the whole thing would come out easily.
If you are out of town, but have family members in town, at least give them a shopping list, and perhaps instructions how to build a few things you might want in advance.
As mentioned by myself earlier, if it doesn't go forward, and you can't get it to pull up, then try pulling it backwards. Figure out how to make it work.
Vacation Days????
And, make sure the clowns that got it stuck are there helping.
