I drove a 13 Ram 4 door 4wd with the Hemi the other day.It rides and drives better than I expected.I will say it was a little soft down low but once you get above 3500/4000 rpm it really started to pull.

I hope you noted the mileage of your vehicle when dropped off.Several dealers around here have been caught abusing vehicles when the owner left a hidden camera in the car during service visits.
