There is a guy on perth4x4 and probably on here to that has a GU ute with the winch mounted between the chassis rails behind the cab facing backwards then has 2 pulleys at the rear where a 3rd block can be attached for rear pulls. The cable then runs through the left chassis rail and up to the front of the vehicle for forward pulls.
Very clever set up and the winch will always be pulling thru one block at least so less strain on it.
