My dmax is going great and is running at 10 lt / 100kms towing a 1.5 tonne camper trailer ,it sits under 2k rpm on the highway in top gear. It cost me $425 for a 10 k service but I had an engine oil change done as well as the diffs oil , so far so good I will give all the fuel data at the end of the trip in a couple of months 😎😎😎😎😎😎. I am more Han happy with the dmax it has done everything asked of it easily on and off road other than tearing the side step of in some crap country but I managed to get it back on and will be putting it on the list of things I may change when we get home ....Matt
