Before I took on the Uhaul trailer, I recorded my gas mileage. Gassed up on the south end of my town, which is about 12 miles from the interstate on-ramp in heavy morning traffic. Then lots of interstate driving. I figure somewhere between 20-22 mpg I'm averaging, but that was through the entire state of WV on interstate 79 which is up and down and right curve left curve constantly, so not to bad, in my humble opinion.
