You can change the weight of your Vanagon and see the resulting rolling and aero horsepower requirements. You can add on the square footage frontal area of your plastic box and see the resulting hp requirements. It will do everything except maybe get you elected Queen of the May. (According to some tech geeks, the measured coefficient of drag for the Vanagon body is 0.75, and the rolling coefficient is 0.014.
