If price was not a consideration, Gas or Diesel?

I considered a gas dually when truck shopping. Worst thing about them is the lack of pulling power I was going with higher range gears to save on gas. Bumper pull was just about the same as my 2016 f150 with tow package. Made it a no brainer to go diesel for me. I wanted a truck that could haul a tc and pull a big fifth wheel.
