Turns out we didn't need to spend that much on the rest of the accessories because the tyres did their job better than I expected.
We did a trip up the cape and back through Birdsville last year. So we bought a cruiser dual cab. Then a winch, Maxtrax, recovery straps, puncture repair kit,etc, put on a set of Cooper Stt's and towed the camper. Turns out we didn't need to spend that much on the rest of the accessories because the tyres did their job better than I expected. And I've run Cooper tyres since they were introduced in qld.
