Hey guys I'm new here and hopefully will stick around if I get the new girl. I currently own a 05 Chevy 2500hd ccsb which I have had since new. I am looking to pick up a 13 2500hd ccsb duramax. I have never owned a diesel before so tell me what to look for when I go to test drive. Any info is much appreciated!! Here are some pics, 37,000 miles and motor looks stock.
