Thanks for all the replies guys! Triple Threat your information is exactly what I'm looking for! I hope that someone with a 2012 has this type of information. The reason is that auto trans is now a 6 speed! The 2012 HEMI is also up to 383 horsepower and 400 ft lbs of torque! This doesn't compare to a diesel but the the price of that option along with maintenance costs and fuel prices doesn't make sense for a truck only used 2,000 to 3,000 miles a year to tow a racecar!
Thanks! John
