Anyone have a Dakota with a 4.7??

i have a 02 ram with the 4.7 . i like it for the most part, plenty of power. pushed my truck through the 1/4 at 16.8 @ 82 mph. all stock with 3.55's. just saying haha. i was a bit dissapointed with the fuel economy though, i get like 12/13 city and maybe like 16 or so highway. that is in a full size though id like to see how much better a dakota would get moving and what kind of mpg's with some fuel eco mods
