The older one is pretty worn out after 478K km. The main issue has been that it is extremely heavily loaded, and it has actually worn out the body mounts moreso than the suspension components. This is an agricultural service vehicle, so does a lot of kms on dirt/gravel/clay roads at high speed, but other than the sandblasting effect on the underside, it's still in pretty decent condition on all the driveline components. Being that we're still on the factory original turbos and injectors, my guess is it's not far away from a major dollar overhaul. I was looking at buying it off the company for a sweetheart deal, but I have already rebulit one of these motors and have no desire (or money) to do another anytime soon....How do your trucks hold up down there on your roads and conditions?
