Only had it a week so far. 1200 miles, so it's nowhere near being broke in. At the campground for deer season, and driving a combination of back roads with lots of hills, and maybe 20 miles one way on a flat 4 lane highway with a 60 MPH speed limit. Been averaging 13.5 to 14 on that round trip daily, about 45 miles total one way. I got about 14.5 on the trip down here, about 100 miles, mostly interstate. I don't plan to hook the camper until late spring, early summer, but if I manage to get 9 mpg while pulling it I'll be happy. If I'm able to level out at 15-16 on the highway (not towing) once it's broken in, that would be awesome. Time will tell.
