I recently purchased a brand new Ram 2500 series Power Wagon( the Taco Wagon). It's got all the bells 'n whistles known to man - plus Spanish leather seats & interior trim. The price was beyond OUTRAGEOUS. But I finally figured it out - there is no way, that I know, that I can take it with me when I go.
I did not buy this truck to get good mileage. It is strictly for fun. However - on a recent trip up north, thru the mountains, I got 18 mpg. And that is with 4.11 gears and a 410 hp Hemi engine. The round trip is 265 miles.
That is more than adequate, for me. And I go back, at least, 25 years every time I drive it. It is a REAL blast.
