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

Lol, good one fish!!!! Just wanting to know if anyone has any real world experience with the change. I like the ford but the gas mileage is killing me
