While that's a correct statement, we typically want to go through life in one of our FORWARD gears.
I've seen a lot of people with receiver hitches in the front AND the rear, and a receiver mounted winch, that they carry inside the vehicle, and mount it where they need it, when they need it.
A little place near me (Pickle Gulch, Colorado) is impassible, when it's covered with ice, unless you're winching yourself up it. Rear winch just wouldn't cut it for that.
