Welcome. I am new to the forum too. I just purchased a 2012 RT last month, and I too have a 100 mile commute to work. The RT makes for a much more enjoyable drive to work. The MPG is not as bad as I thought, my previous SE averaged around 22 (at an 80 mph average). My new RT is the same, and could be better if I could drive 70... but is really hard to do.
enjoy your new ride!
