I traded in a Ram 1500 with a 5.9L (gas) engine and my new 5.7L Hemi (w/auto)completely blows it away. 100 more HP and about the same gas mileage. I average around 11 MPG around town and get aroud 16 on the highway (12 towing a 4000 lbs TT). The new 2500 is exremely well designed inside and out. I have a Sport model with leather bucket seats and fixed center console and it's very comfortable and loaded with features. My wife is jealous becuase it's more luxurious than her car! Navigation and satellite radio are both fun extras that I would have never considered but ended up really liking. My only complaint is the low ride height of the 2500 2WD nose and the unattractive stock wheels.

Ugly stock wheels (no 20" option on HD) and poor gas mileage
