Ok guys so im really intrested in buying a duramax and had a few questions. This would be my first chevy (or GMC) and first duramax. So what are the pros and cons of each year truck? I don't want a brand new truck so i think the LMM is out of the question. What ever truck i get will not stay stock by any means. I have heard the 01's dont have the piston issues that the others have. Is this true? Just trying to narrow down my choices and make it easier to find the best truck for me.
