I do believe also that the tow car helps to smooth out the air flow. I have often thought about a flexible fabric that would attach to the top and sides of the MH and then attach to the tow car producing a more laminar flow and keeping the tow car clean at the same time. I have tracked every gal of gas over 80k miles, 20k with no tow and 60k towing and see no difference in MPG. Individual reading range from a high of 12.6 to a low of 5.7 mpg but I average 8.6 mpg towing or not towing a 2500 lb Toyota Corolla. So I believe (rightly or wrongly) the better flow from the tow car offsets the weight of the car. I know others say the tow car reduces their MPG by 1 MPG its just not my experience.
