A guy I work with had a 13 that he just got rid of. The 3.6 and the 8 speed are a good combo, he always said he got 30 mpg in it. He traded it in for a R/T a few months ago, I don't think he ever had any issues.

I like the 3.6 in my Ram. Its a stout little v6, but the 8 speed really helps to keep it in the power band.
