Such an interesting thread... I just purchased my first diesel and before anyone says anything, no I don't NEED a diesel. I don't tow/haul much of anything. However, after having a Gladiator for over a year, then a TRX then a TRX Sandblast edition, I knew I had to be in a truck. The TRXs are incredible trucks, comfortable, versatile, and a blast to drive but 8.2 MPG daily is just tough to swallow. After having a Sandblast for a month, 100k sticker, and 8 mpg, I bought my 22 2500 Mega Cab, dropped my debt and my MPG is 17.2 as of this am, with 350 miles on the truck. So yes, the Hemi might be less expensive than the Cummins when you factor the two but when I compare it to my previous vehicle, I'm ahead by a lot. The other thing these things never really take into consideration is the resale value where diesel will destroy a Hemi, I know cause I was shipping the used market before striking the deal on my new 22. If they ever put the new 5th Gen cab on the 2500s, I MAY consider a PowerWagon as it's more of a truck for me, but the extra room of the Mega cab makes life with two small kids a lot easier.
