Ok, folks. This theory is untested, but I have some counter-intuitive suspicions. This post is an adjunct to my prior post on using cruise control for improved mileage.

It *seems* that my TCH gets better gas mileage at 65 miles per hour rather than at 60 MPH, and that my MORE CONSERVATIVE freeway driving appears to net worse MPG results.

My theory is that a 3,600 pound TCH traveling on the hilly freeways of San Diego MAY be better able to sustain greater ROLLING MOMENTUM at higher speeds (to conquer the next hill) than the mileage I can achieve by efforting over each hill at lower speeds. I believe that rolling momentum would be more significant for heavier cars, and therefore more crucial for a TCH than for a Prius.

Any facts/data to support my speed vs. rolling momentum theory and their effect on gas mileage?
