mileage question
I just completed a round trip with a flat deck fifth wheel on for 1200kms. Loaded a car and parts and drove back.
Trailer weighs 3500pounds + the car weighs about the same with about 5-600 pounds of parts.
I hand figured it out to be just shy of 13 mpg, hand calculated. Am I wrong in expecting more?
