Most of the time people exaggerate their mileage, go by inaccurate MPG gauges or are simply bad at math. You just have to read between the lines and not believe every claim out there. 15MPH towing with a gasser is pretty optimistic...
He tows an Airstream. Big difference in aerodynamics. While I suspect that at 65mph he won't get 15, I also think in the right conditions its possible he can get it at 55. I emphasize, the right conditions. No wind, or a tail wind, flat terrain, moderate temperature.
