I live in Northern Utah, anytime we go camping, fishing, or hunting, we have to pass over at least one mountain range. Empty freeway mileage ranges from 14-16 depending mostly on speed, hills don't seem to reduce mileage as much as I would have expected, when it's empty. Towing our 10k 5th wheel, with a 3k lb side by side behind that, I get 8 ish MPG. For reference, my Dad has a 2016 with a 6.7 Powerstroke, and he gets 10 MPG pulling a similar setup.

Do you feel the Deisel is worth the added 2 mpg over the gasser when you add in the diesel torque and cost of diesel?


For me, and what I do with my truck? No, I don't feel like it's worth the extra cost. I can easily go the speed limit pulling my stuff, how much faster do I need to go? Cost wasn't the deciding factor for me though, the thought of having one of the many exhaust after-treatment issues leaving me stranded on a mountain somewhere was concern #1.

I should add, my Dads truck that I mentioned does not have the 10 speed auto, so a 2020+ Powerstroke would likely get even better mileage.

If I owned a 45' toy hauler, then I would have gotten the 6.7, but I don't, and won't.
