Just bought a 2012 mega cab 4x4 Big Horn and I am New to Dodges. I always owned Chevy's. After I bought mine I noticed some had the high out put badge and some didn't. Are there two different versions of the 6.7? Also curious as to where I find which ratio rear able I have. On the Chevy they list it on the window sticker, but not on the Dodge's.
