2011 dodge ram reviews needed

We just made a 560mile round trip to Corpus Christi this past weekend and got an average of 20.1 mpg with our 5.7Hemi. We kept it at around 75mph with the cruise control on as much as possible and had the A/C blowing the entire time. The mpg was climbing the entire trip and I believe we could have hit 23+ eventually. We have really loved our 2010 crew cab!
