An extra 50 miles would be nice, but the 33 gallon tank would really make a big difference over the 23 gallon tank my Laramie has. I made the incorrect assumption that my truck would have the 26 gallon tank as standard, but for some reason they decided putting a 23 gallon tank in a crew cab truck with a v8 hemi would be a good idea. I admit I should have asked about it though. I'd get the biggest tank you can.The hunt has narrowed down to 4 vehicles thanks to all of your help on this site. We really thank you all.... How important is it to have a 26 gallon fuel tank?
