At 58 K miles we traded for the duramax but the 8.1 was running like new with no issues. Oil use was minor . Trannie was great for going down mountains. chevman retired from rving with an awesome 05 3500 duramax in the garage waiting for another chance maybe Re: Cummins Hit with 1.7Billion for Emissions Defeat Devices our world is falling apart. chevman Re: Cummins Hit with 1.7Billion for Emissions Defeat Devices more power over the people. chevman
