I wrote you a long response, then realized I don't care what you think. I'm not a liar, it does what I said, but my area is very flat. I can buy whatever I want, and chose the gas version for a myriad of reasons. Anyone with google can find out why. If you want a diesel, I suggest another brand. If you want a good towing truck that lasts, for a good deal, choose the titan XD 5.6 IMHO.
