It has only 1300 miles on it now.
Just adding this note in case a future searcher encounters this thread.
Taking our first long trip yesterday I checked the gas mileage between Morganton, NC and Cookeville, TN. We were cruising on I-40 between 55-60 mph and got 9.05 mpg. I was very pleased as the cargo bin was loaded and we had a full water tank, but we were not towing anything. This route also included passing through the Blue Ridge mountains on very hilly terrain.
