Hello Ot..
For large Whitetail, I've use a golfball, rope/chain, and truck to remove the hide. It takes a minute to do it. Basically hoist onto and hang carcass head up onto a stout limb. Cut back (release) a section of the neck hide insert golf ball secure rope around golfball and tie to truck bumper. Make relief cuts on leg knuckles. Slowly drive away while peeling hide from carcass.
Moose would probably be a bit much to do it this way, since most hunters in the field don't have a cherry picker sized hoist with them. LOL
Peace
