[Yachts]

  I'll see if I have a pic to explain it but in the meantime I'll try to explain.. The tow truck extends what looks like a "t" under the coach to where the cross piece goes to each side of the coach . On the "t" there is what looks like a small ramp that goes under the tire. They then attach another piece to the "t" that goes around the side of the tire and it has a small ramp that is tightened and slips under the back of the tire.then the t is lifted up
