My calculations are entirely based on the data that you posted based on an average fuel economy of 10 mpg. If your fuel economy is significantly different than that then my calculations are wrong ..... that is why I have been asking you over and over for your actual fuel economy.
Well then snip one of the maps I posted earlier, open it in paint, and plot away. However, instead of varying speed which I do not do since I set cruise control at 65 mph. Vary the Nm/kw to tow for the different grades/drag since my route is hardly ever flat most of the way. It consistently varies which varies the Nm needed to tow, not the RPMs or speed. When I finally do get to flat land closer to the coast, the wind starts becoming a major factor.
