Mate I read that thread also, great read.
I reckon the tug has a fair bit to do with it for something like that. Double lockers, lots of winching etc. Also a little less regard for the gear and taking the risks, however calculated would help. I believe Darrens KK is well used and sports quite a few battle scars. However it has taken him and the Fam to some amaizing places.
We will have to catch up somewhere one day mate. At least if we taravelled somewhere in convoy my 1HZ wouldn't be holding you up. I have a thread on the old girl in the my 4wd section. You should post up some pics of your when you get a chance.
