If you have never harvested a moose prior, you have an interesting time ahead. If you manage to knock one down, when you walk up to it, the first thought through your head will be "My God, what have I done and where do I start". All the gear in the world won't prepare you for that moment. Best done with an experienced moose hunter first couple of times, if at all possible.
Picking one of those brutes into managable pieces is a chore, not best done on one's own. Not impossible but an astonomical amount of hard, messy work. Can be quite intimidating for the novice.
Couple words of advice...
DO NOT shoot a moose in the water, not even ankle deep, ever!! Scare him out first if necessary. (unless you can get something with a winch to it)
DO NOT shoot your first moose at last light, or you are in for the worst night of your hunting career.
Now go forth and have fun slaying yon swamp donkey.
