I am looking to upgrade from my 2000 Quad Cab 2500 V10 to a 2010+ 2500, my main reason is to gain more back seat room for the kids. We plan on getting a travel trailer in the 30 foot range next year for family outings. I have been looking and I can either get a fairly low mileage Hemi or a 6.7 Cummins with a few more miles for what I am looking to spend. I know the diesel would be nice on long trips with the camper, but I have read all sorts of horror stories about the emissions stuff on them. This wouldn't be my daily driver, but would see daily use in the winter when my Charger is parked. My drive to work, and anywhere really, is 17 miles of all highway. I like the idea of the diesel, but do you guys think a Hemi might be a better choice?
