I have a 1992 Mitsubishi Triton 3 litre V6 petrol engined 4wd ute/pickup , bought it with 200,000 klm's on it and it's just clicked over 400,000 klm's (new motor in at 360,000 klm's , was towing and carrying stupid loads so it might have sped up the engine wear) . Apart from wearing out the motor had absolutely no drama's with it , there's a synchro on the way out in the gearbox but it's still the same as it was when I bought it 200,000 klm's ago . The gearbox has blown a rear seal around 100,000 klm's ago and drove about 5 klm's without oil before I worked out where the noise was coming from , fitted a new seal , filled it with oil and it's fine , the gearbox on the V6 is a truck box (Mitsubishi Canter , probably different name up there) .
I've towed a trailer with 3 tonnes of scaffolding steel in it over a mountain range and also carried a 1.5 tonne walk behind compactor in the back of it without the springs reversing so it does everything I want . Might have to move it on soon though as it only seats two (it's the extra cab/king cab version with room behind the bucket seats) and there's now 4 of us , will be sad to see it go really .
