Just thought I'd start a new post about the new 5.7 ltr "HEMI". I know they've been out for a couple of years now but it's still a pretty new design. I've always heard not to buy a first year production vehicle whether it be a new drivetrain, structure, or both because there always seem to be a few problems arise. So now that they are being put in everything from the largest 1 ton dodges to the Jeep Cherokee and evan the cars, what is your experience with them?

I have had mine for a year and 11K miles now.
2004 Dodge 2500 4x4, Quad Cab, Short bed, Laramie, 5spd auto, 4.10's
I haven't had a single problem with it and haven't been to the dealership except to get a new oil filter every 3K. I put an airforce one intake kit and Flowmaster cat back dual exhaust on it to help it breath a little. It sounds great and runs super smooth. My mileage now is about 12.5 a gallon and pretty much all town/city driving where I live in southeast Alaska. I don't really notice a difference in 4x4 or not. January was pretty much all 4x4. I did go up to the Yukon this last summer and got 16.5 mpg throughout the trip. I am not displeased with this from a truck this size. In High School I drove a 1968 GMC 1 ton 2x4 that got 6mpg with a 350 small block. Or maybe my foot was heavier
Also I have always used only regular 87 octane fuel. I know my manual suggests mid grade 89, but is says 87 is fine. I haven't had any negative impacts such as knocking, hesitation, rough idle, etc. I will try and post a picture of truck when I figure that out.
