I haven't had my TT long enough to compile figures, but here are the figures on my Class C that I had for 10 years.
60 mph = 9 mpg
70 mph = 6 mpg
That was a 17% increase in speed with a 33% decrease in fuel efficiency. Fastest may not be your best choice, for a plethora of reasons.
Thanks for supplying the numbers.
It's actually intuitive and the simple law of physics and aerodynamics specially with flat fronted RVs. I'm still finding the sweet spot of speed and mpg on mine. And with high head wind, I don't even fight and stay on cruise speed even if it drops slightly.
