higher rpm's with high vac #'s or lower rpm's with lower vac #'s?

I use higher gear which gives lower rpm and lower vacuum reading. I just took a trip over the weekend that was 610.4 miles round trip and used 12.423 gallons of gas in an '88 Escort. This comes out to an average of 49.13 mpg and about 100 miles of this was mountains in eastern TN and western NC on I-40. I was normally driving 55 and ocasionally reaching speeds of 60-70. There were two passengers in the car with me and a tool box in the trunk that weighed about 100 pounds. The only time I used a lower gear was when I needed the power.
