I just finished reading this thread and was thinking the same thing.
In fact the only reason I read it was to try and understand the bugging out thing. In Australia it just not a thing that crosses anyone's mind. And we do have our share of reasons to bug out. Mostly natural disasters.
Starting to see a few around now. Have not been out very long in Australia.
There has been quite a few 200 and 70 series wagons cut down into duel cabs over here. It was the only way to get a full size duel cab. Unless of course you wanted a Land rover.
