6.4 ford or a new body style 2010 dodge 6.7 or duramax 6.6. I own a 06 5.9 cummins 87k. I love how it runs hate the ride and the interior. I know their is a lot of people who have owned different brands and are not die hard ford or dodge or chevy fans. I don't want a brand war. Just honest likes and dislike of the trucks. I like the dodge warranty but i don't think i can drive any of these trucks stock due to fuel milage and emissions. I want a truck with under 40k and want to own for a few years with little problems.
