Trey here in Deep East Texas. I am a brand new Duramax owner and first time diesel owner. Just purchased my 2013 2500HD Z71 4x4 on Saturday. Will be used to pull my 30' TT along with mostly light driving. Im excited bc i can feel how much power it has in.so, being new to diesels and to Duramax, is there any thing right off the too that i should know? It is stock at the moment and plan to keep it stock for the time being untill i get some time in it an then i will go from there.
