I have a 90 model 4.2 diesel ute done 450K kls and very heavy farm work hauling 100 ft goose neck boom with 2.5 tonnes of chemical, Still does not burn oil and only recently turbo,d it. Still origanal drive train gearbox ,diff but change oil reguarly . Also pull 16ft bogey trailer with up to 3 tonne of lambs and that turbo has really helped with this task. Need more cooling though cannot run a/c when fully loaded. Great model and indestuctable .Cheers Ian
