Well, I finally checked my fuel mileage travelling with the genny, front AC and fridge on...............6.8mpg. That is only on 1 tank so may not be totally conclusive. I was on interstate for about 1/5th of the drive and the rest was in the Boston Mountains, 2 lane in AR.
That is about the same mileage I got with my 350, dually, crew, V10 pulling a 37' toyhauler.
I will add that my driving habits are using the cruise set at 60-62 and let the tranny and engine do the work.
