I was traveling from sudbury to manitoulin island.
Truck has the 8 speed tranny and 5.7 l hemi, it seemed to like to stay in 7th, around 2500-3000 rpm.
I was in tow haul the whole way which hold the gears a LOT longer.
I not concerned about the gas, it is what it is, was just kinda surprised at the mileage.
I also had 20 gallons of water and 5 gallons of gas In the back of the truck.
Trailer pulls straight and true as it should.
