I occasionally see a lifted Jeep with this same "nuts" setup on it's hitch on my commute.
The only better setup I've seen was last weekend - a lifted Cummins Dodge had a pair of pistons hanging by the connecting rods (sorry , no photo - I'm poorly setup while driving).
A couple years ago I saw that same Jeep get the "death wobbles" going about 40 MPH - it was violently taking up both lanes of a narrow road.
That just reinforced my bias that I don't want a Jeep.
