I don't hear about too many people who get more than 12 towing anything, gas or diesel. Most trucks with a load behind them (say towing jeeps) are usually right around that 8-12 mpg mark. Gas or Diesel.
Towed a TJ up to snowfari and I got about 14mpg with my duramax and I was doing about 78mph. This was hand calculated and the truck was sitting idle for about a total of 1.5 hours during the entire trip.
I do like the idea of a Diesel half ton. It would be a few years but I would probably be in that market.
