I wouldn't skin it in the field. I'd gut it immediately, but skin it either back at home, or in camp (if you have game bags ready). But you really don't need to skin it unless it is pretty hot and you're going to cool it off quickly by quartering or icing it.
You only have 3 days, so I'd make arrangements to find a processor or someone who cuts their own in case you get one, that's close to where you'll be. Then later, when you get more time, you can get a lot of info on how to cut them up yourself, if you'd like.
There are lots of ways to do it, it's not hard, and freezer wrap/tape are cheap. And a grinder's not a bad thing to have if you're going to be doing a few.
Just some thoughts....
Take Care,
