Nice! I figure I might be close to the 17mpg I normally avg but I didn't calculate it like I usually do, just saw how much was left and the mileage. The car weighs a bit over 3K lbs on it's own and figure plus the trailer etc probably somewhere between 3500-4000lbs and I had my VX loaded with my fullsize spare, tools, etc for my long trip. I was very happy with how ol' Sylvia handled it with ease! About 65 and the trailer started to sway a bit (the tow dolly was a piece of junk) so kept it between 55-60 the whole way
