I can certainly relate. I have not forgotten to fill up, but like others, I have found planned fuel stops to be unavailable (closed, construction, out of fuel, etc.) and have driven some long distances without services while consuming a gallon every 8 miles.
Because of those "long miles" I now have a TransferFlow 30-gallon refueling tank/toolbox combination. I can carry tools for repairs, recovery gear, fuel for my generators, and have plenty of fuel so that I don't have to drive any more of those white knuckle miles, scanning the horizon for what looks like a sign attached to a gas station.
