nate, my 4x2, is more 4x4 then most people want to believe.....
possibly not here, but in general... you probably wont see too many 4x2s built like mine, if any without some major crazy longtravel suspension or somethign converted to a tcase with a front axkle
you still have a pre-runner type 2wd, i betif you tossed a 4.10 in that rear you would actually get better mileage
