New tow vehicle...6.4 hemi or Diesel?

I have a 6.4 in a 3500 ram, it pulls everything fine, but it is a thirsty pig, 10 mpg empty or loaded.
It sucks so much fuel it is only used for towing, no daily driving this truck.

Ive got a 13,000 lbs,box truck that does better than that, and its got the worst diesel ever, the 6 liter ford.
