Hi Weeds
fresh water can be gotten at orchid beach servo/shop dont know if its potable also at the resort and a few other spots
i towed my little cub with the ln167 3ltr non turbo last year with no problems at all.
the cub loaded would have been around 400-450 kg and around 200 kg in the back of the ute.
the bit that had me worried is the camper only has 13" wheels, dragged the axle a bit but was ok
was talking to a mate who wants to go this weekend and has to hire a 4wd, the 4wd hire mob told him that driving conditions are bad atm
being after the school holidays i would probably agree but you never know
edit must add we stayed this side of Nagala Rocks
