Ok so its not on a Jeep...but it is custom made and one of a kind and might give you some ideas if it were scaled down.
I call it
The Tombstone its taken out 3 deer to date.
This is an old picture and it has since been repainted with gravel guard and had more tow points added, I can't remember its exact measurements but it sticks out around 2 feet from the front of the truck (in the center) and weighs around 200lbs (including the winch) give or take.
