That'd be amazing if an 80,000lb big rig got better fuel mileage than my co-workers durango which gets 12mpg Would really show how completely inefficient some vehicles coughdurangocough are

Ever noticed the massive airdams on big rigs? I suppose the side skirts are just a logical extension of the aerodynamics they started at the front of the vehicle.
