Interstate vs. secoundary roads?
I was wondering if driving the interstate using cruise countrol would save much gas verses the slow down, speedup of going thru towns? My truck seems to have a sweetspot towing of 63 mph.

I drive the interstates to get out west,1800 miles one way, to family. We used some secondary roads this year and I found some were really rough. The 1800 mile trip usually takes me 5 1/2 days. We used more than usual secondary roads this year on our 50 day 7k mile excursion. I didn't follow mpg between the two but got about 11mpg for the trip.
