To draft or slow down?

I suggest you work on Pulse & Glide. Running the RPM that high is a KILLER to mileage. Pulse & Glide is a good way to overcome that. I've run that same highway trip several times.

57 mpg - 70mph drafting P&G
43 mpg - 65mph cruise-control
75mpg - 50-60mph P&G

That means gas from 50 to 60, off the gas 60 to 50, repeat?

That's right. Shift into Neutral for the glide part. Pulse at medium-high throttle. Is yours an automatic? Leave the engine running for the glide. If it's a manual, you can shut it off and then clutch-bump to start it back up.
