I've been driving Rams since '96, so I am definitely an enthusiast.
The look of the new Ram is just a little to refined for me. I look at it and get the feeling of family car or station wagon with a truck bed on it. The grill being "wrapped" around the lights dont excite me either. There's not doubt they are really nice and I could get used to it with the exception of one thing.
The clincher for me (and I just dont understand why) is the hood badge. It just irritates me for some reason. A 5th gen parked next to me the other day, and I couldn't not focus on the hood badge when I was walking up. It was then that I decided I just couldn't do one. I cant drive something everyday that is irritating. I'd have to fully replace the hood if I were to do a 5 gen.
When walking up to my truck, I want the feeling of "that's bad a$$". All in all, it's a nice truck, but not for me any more.
