Hello, I would like to get back into the diesel game but want to do some research this time before I purchase. I now have a 6.0 Chevy 2500 but with driving to work and towing bigger load I want to go back to diesel. I previuosly had a 2008 6.4 f250 which I loved but I was not a fan of all the emmisions crap on it and the potential problems . I am looking at a pre emmisions Chevy 2500 with the new body style which is the 2007 right? Any major problems with the model? I'm also debating on a new 6 cyclinder turbo cummins, around 2011. Are the newer cummins with the emissions equipment problem prone like the 2008 6.4 f250? I just want a more reliable diesel, I'm also I'm California so I can't take off the emmisions equipment. Help a brotha out please.
