The trick is learning how to keep mds engaged. It's easy to hear in my 05 hemi RT Magnum with Borla exhaust. The exhaust goes from a low rumble to a almost silent whoosh when it hits 4 cyl mode. I wish my 05 Ram had it, but driving my friends 06 4x4QC Laramie, you have to really pay attention to hear it kick in. On a long trip, never exceeding 65 mph, his Laramie averaged almost 23 mpg. My non mds 05 probably would have gotten 18-19 babying like that without mds. So yes, you can get great mileage with a hemi, however, you will be bored as hell doing it.
