Like others I would go with the 350 and a 4x4. It's a mistake I made and now regret not getting a 3500 in my Ram, but with that being said I would never recommend a Ford diesel around that build year. We have two 2007's and two 2009's on rescue vehicles at work (wasn't aware they went from 6.0 to 6.4's, since they both brake down with similar regularity). They brake down often and have constant issues with the motors which has forced us to purchase replacements at a considerable cost and much sooner than expected hitting our budget hard. It's a shame that Ford put out such a poor product and will not stand behind it. Things just haven't been the same since the very dependable 7.3
