I feel a lot of guys buy the Hemi because its the biggest available, even though most wont use all of its power. I have nothing against big power, but dont knock people for not buying the craziest amount of anything just because it can be.
Great way to put it. If the ram had an available 6.4L hemi then most people on here would buy that and say the 5.7L sucks. The v6 is more than adequate for daily driving. Not a good racer but if you're not into that then you don't need it.
Personally I wouldn't get a v6 in a big truck either way because from my experience it doesn't get better mpg anyway, but I won't knock you if that's what you want to get. For example my 4.7L gets ~17mpg city and 20+mpg hwy. I don't think the v6 does that well, and I'm a quad cab.
