I honestly love the look of the sportier trim new Durango's. I'd of course make the irresponsible decision to get one with a hemi for the one time a year I decide to move my trailer, and don't feel like getting my truck out. lol but with those 8 speeds i think the mileage on either engine is respectable. my wifes daily is a Charger R/T with the 8HP70, and it averages damn near 30.
I bet one with a pentastar would do just fine!
