Hello. My name is Greg. I am not a trucker but a diesel mechanic. I worked on trucks for over 10 years but have been out of that industry now for about 8 years. My specialty was the ddec III & IV detroit 60's. I'm just here to try and catch up on the new technology out there and offer any advice I can on the older 60's. I'm considering getting back into the truck repair business because that's where all the hi tech stuff is. In the oilfield now. Nothing but dinosaur mechanical equipment.
