One word.......Diesel
My dually (RAM w/ 24V 5.9 L Turbo Diesel) gets better mileage than most cars while pulling a 18 foot trailer at 120KPH If you want even better stay at 100. I can do Bowmanville to Grand Bend four bikes in the trailer for under $50 in fuel. Bad part is truck will cost you to buy. Good part it holds its value better than a gas truck.
