Hello everyone.
New to the forums.
Previously owned a 2002 1500 4x4. Decided to get something that would pull an RV a bit better.
New owner of a 2012 2500HD Duramax. NO real problems except for the EGR and DEF *and a stupid NOX sensor after the first couple months. That's since been solved and should never have those issues again.
Only upgrades done to the truck so far look to be the EGR and DEF. (i had done) and I installed a T*** tank for a few extra miles between fill ups.
