Slowmover, on a somewhat related note, the reason I found this was I was trying to figure out what Dodge Cummins has the best potential for high fuel economy. Your 2004 seems like a good bet. I need a bigger cab then the 94-02 offers, unless there are crew cabs out there I don't know. I'm not above a swap into a Ford or Chevy either. I'm also OK with whatever mods might help, no emissions here and I don't want to make big power, just like a DPF and EGR delete for economy and reliability towing about a 6-7000 pound travel trailer.

My 14 mpg towing that Hi-Lo has gone to 9 mpg with the new Forest River hybrid. I don't think that's unexpected. I'm also thinking about a 2008 3.0 GL Mercedes CRD but I don't want the rest of the expensive problems that surround those things. The Ecodiesel Dodges and Jeeps are just too expensive still.
