The owners say they get about 10 MPG of diesel but that seems incredible to me. My truck gets 15 mpg and it is ¼ the size of those behemoths. They are 40 ft long and can weigh from 15,000 to 30,000 pounds. They have a flat front like a brick being dragged through the air. How can they get better than 6 mpg?
If you have or had one, what has been your experience?
