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 use as much Interstate as possible to get to my destination. Here in Illinois, we have a lot of small towns where the speed varies up and down and up and down when traveling the backroads....Gets annoying. But to each his own. :)
