2013 Dodge Ram 2500 5.7 Hemi

I admit when I'm running up a steep grade at near 5500 RPM, it gets the heart racing and my wallet screaming, but having done some rough math at an almost $7K premium (with the 6 spd auto) and fuel costing between $.50 to $1.00 more around my area I could not justify the upgrade. Add in more expensive oil changes, filters and an actually lower cargo weight capacity plus the fact that I maybe get out for 30 nights in a good year I can deal with the noise. Even with changing my oil every 3K and 16 spark plugs every 25 K, I think maintenance wise I'm still way ahead on routine maintenance. I averaged approx 7.5 mpg going to Nashville, vs. what I've read is approx 11.5 for the CTD.
