Thought so,

The reason nissan is at the top is because of its toughness.

It has the strongest driveline of all trucks and the biggest chassy. The Y60 GQ patrol actually uses a Truck box, diffs, driveline to give it the most reliabillity out of them all.

I have also owned most of the trucks above and now a nissan and can say it is by far the toughest most capable reliable 4wd of them all.

Even the 80 series landcruiser uses a small hilux rear diff in the front of the wagon for some reason which is one of the letdowns of the mighty 80 series landcruiser.
