Do it gutless and strap it on to your back. 2 guys will have a moose packed a km in a few hours.
Here you can't go less than quarters on a moose before registration. Not a moose hunter but would assume like most animals they can move a good distance after being hit. Just saying you can shoot a moose a ways from water but they may end up dying in a bog or swamp. I'd definitely want a way to work winches if I were do any kind of moose hunting.
