uneek 4x4 are updaiting their bar to suit the new facelift, and its not just tube.

you dont need lift if you chop guards, and for some tires they fit in standard guards without lift.
9500 lb is as big as you want to go, and 8000 is a good size if your realy stuck down. a oldschool hand winch or trifor is more versatile and wont kill the battery in the jim, with its tiny 60A alternator. or you could put in a falcon 100a alternator.
a bullbar and winch add up to 60kg if you have steel cable on the winch. so the fornt will sag if your springs cant hack it.
jimnybits have short snorkels that fit the 2012+ facelift, because they dont come all the way down the fender.
i have a full rear bar from a now defunct company MIC offroad. their manufacturer is still operating in china, but its not exactly cheap.

i wouldnt recomend building in the fridge, just build a big drawer that fits the fridge and a tray on top of the drawr.
keep in mind you only have 345 kg from tare weight to GVM, including people.
