Jimbeam, you just brought up a very good point, you say you'll only use it a few times.
Thats a lot of money and weight sitting on the front of your 4x4. I'd personally be putting a locker in the front.
you may need a suspension up grade as winch combo is 45 kg plus, so theres more fun vouchers gone
Possibly a 2nd battery as well, all adding up..
