Well after much faffing about I decided it was time for a new tug. The Dmax is at 180,000kms, and while super reliable, is showing it's age and all the dirt roads.
So in keeping with my tendency to buy Chinese on ebay I bought this...

A demo GWM Cannon Ultra with 700kms on the clock and a factory tow bar - hopefully without the advertising - for $44k. It will need new all terrains and a canopy but that should still be not much more than a non demo model with 600 less kms
The one long range tank I could find only adds 30l so it might be jerries this time around. But the extra 100nm of torque should be very welcome.
