Earlier I posted that my RV's sweet spot is 62. I ran a test, kind of, back in 2011. We were going to Yellowstone National Park from Tennessee and had a limited amount of time, so I drove 72 to get there faster. That is about a 16% increase in speed.
I had a 33% decrease in fuel efficiency. My consumption went from 9 mpg to 6 mpg for that trip. For me, that was unacceptable. Now, part of that may be the Rocky Mountains, since most of our other driving is on the plains or the Smokey Mountains, but part was the speed increase.
And with my rough math (using a general 1800 miles between Tennessee and Yellowstone), that was 4 hours of drive time saved at the cost of 100 gallons of gas. About $250 using today's national average, or $62.50 per hour.
