I don't think you will see a different. We did not notice a difference when we install a 2" lift kit and were towing with a sienna. But I'm sue we took a small hit around 0.1 MPG. But it is so hard to tell. We will see up to a 2 MPG variance depending on direction of wind, change in travel speed by 3-5 MPH, hills, and how close we are to sea level.
