Good looking patrol. Congratulations
IT looks like it had a winch at some point. If it doesnt have a suspension already to accommodate the weight of that bumper and if you want to add a winch again. I would recommend a suspension. The Original suspension wont last with the added weight. And since its a 4.8 you will need jerry cans and a place to put them
You made the right choice between the 2 anyways.
