Empty
mostly 2 lane country roads, I average around 17 mpg
Highway (60-65 mph) 19-20
Loaded with camper in sig
On a 4443 mile trip from PA to Yellowstone and back, fuel used, 318 gallons of diesel. Worst mileage, 12.3 mpg (head wind in South Dakota). Best mileage, 16.9, but that was only half a tank with half of that spent driving 35-45 MPH in Yellowstone and the other half the downhill run to the East entrance of the park and into Cody WY. Best all highway tank 15 mpg with a quartering tail wind across Indiana and Ohio. Average MPG, 13.97.
