Rating : 3 unfortunately, the ladder of the rooftop tent was not complete. (the second part, to lengten the ladder to reach the ground, was missing we had to climb like acrobats to reach the tent)
The rental company in Darwin should have checked the equipment better before renting it to us...
And for the hot circumstances in mid-november, the fabric of the tent, including the netting, was too thick to let air through.
Beside that, the driving was good and we enjoyed the little fridge.
Rating : 3 setup was perfect -- car used tooo much fuel - fridge stopped working one day (to much shaking - fixed by us) - and well more than 400mm river crossing is not legal. :( but car was ok -- 4th gear was hard to get in
