The biggest thing is how far it protrudes when in use (and how low it is). The other is that Class three hitches are only rated at 5000 pounds. I have very rarely had to be winched backwards. If there is nobody behind me to give me a strap I'll rig up my HiLift to pull me back. The other option is to use a Black Rat hand winch with 66 foot of cable. A 3500 # winch is only 30 pounds and can pull 7000 if using a snatch block. A much better solution than a "winch on a tray". For a flatlander the hitch idea may have merit but it has none where I go.
