I know about the Ford thing. GM has put a roof over my head and fed me forever. But I couldn’t afford new and wanted a crew cab and diesel. I have heard nothing but good things about the Duramax engine. From the asking around on the Powerstroke, I was told to find a lightly used 7.3 and stay away from the 6.0…I happen to stumble onto one, so we’ll see how it goes…BTW already changed the CPS on it, hope that’s not a sign of things to come….
