I've put 100k on a 2015 D-max for work, a good chunk of it in 4WD. They seem pretty well bulletproof and pull like a tractor, although they ride a little like one too. We bought a car just a few months back, and the missus managed to talk me into (ie "told me we are getting") a GU patrol, because I was already halfway there anyway, but a new D-max was high on the list for a while.
