Hi everyone! Im new to this forum and looking for honest opinions on the duramax engine line. (Longevity, reliability, issues and best motor) I am looking to buy a duramax with right around 100,000 miles or less. What are things I should look for and listen for. And what would be some modifications i should invest in first. I drive 60 miles a day to and from work. Do light hauling in-between (wood, snowmobiles, dirt bikes, quads). And occasional light trail riding. Looking to get a diesel because of the longevity, MPG, reliability, and the towing power. Thanks and look forward to hearing from everyone.
