Ford to GMC
Has anyone went from the 6.4 super duty to the 6.6 duramax dually? Thinking of going to the 2015 GMC because I like the body style. Is there a power difference??? Thanks in advance

My neighbor just brought home a GMC Denali with a Duramax. The rear view mirror's look to be on par or perhaps even better than the Fords.
The current stock Duramax has more power than a stock 6.4 PSD.
