I'm Jim Smith a ex owner of a 2002 Chevy 2500HD with Durmax for 21 years, great truck but sadly didn't need the HD anymore so it is gone. In its place we bought 23 Chevy 1500 ZR2 with the LZ0 engine, outstanding truck engine combo. Then a year ago bought a GMC Yukon Denali with the LM2 and 69000 miles. Again great combo. Was a member of the Durmax forum for the 6.6 and found great information to help with ownership. I'm looking forward to sharing and finding info about our baby maxes.
