I guess one thing I would be concerned with the new gas motor, is that it is a new motor.Usually the first year or two, all auto manufacturers have multiple problems with the roll out. I have 2010 Ram 2500, Cummins diesel. You can't ask for a better tow vehicle. I had Dodge Hemi a few years ago and like the Cummins much better. Especially, if you're planning on keeping it awhile. They will roll 200,000 miles easily. The short trips are an issue. But I drive mine every day to drop the kids off at school and to the grocery store. It doesn't blow up or anything, just need to run it hard once in a while to clean it out. Maintenance isn't any harder than any other engine. I do change the fuel filter myself every 10,0000 miles.
