Generally the wench is a block to spending money on the rig!��
What engine do you have? Catch can and EGR block is good for a Diesel. Lift with HD torsian bars is a great start. Bigger tyres are good but will muddies be the best bet in Adelaide? I guess you know where you will be driving. I am in WA so mostly sand here. Regardless D22 is a good bus as long as you don't have back seat passengers with long legs. I have 340,000km on my ZD30 now and still going quite nicely. I got a remapped ECU from East Coast Performance and can't recommend that any more highly. You will find plenty of help on this forum brother so welcome
