Have just been to the MotoGP at Phillip Island and documented my Fuel Usage.
Towing My Butsy's Campa fully loaded and weighing at about 150Kg. Travelling mostly between 100 - 110 Km with faster overtaking.
Averaged 6.13 L/100 Km or 38.36 Mpg over the 1700 Km of the trip.
So it means about 301 Km or 187 miles till empty
