I reckon that’s the way to go if you’re sure you’re saving money and your coach isn’t large and harder to maneuver. Since the PP price isn’t posted on the pump, one just has to hope it’s not high. But experience always indicated to me that they were area-competitive, and the lack of other customers/lines was worth the risk of a few cents. You might look for Freddie’s along your routes; they are common enough, have decent prices, and what I’ve seen is just B5 (admittedly I don’t routinely look while getting gas).
Yes, if your Gas Buddy proffered the diesel types available like Pacific Pride’s locator does, that sure would be helpful. You might contact GB re. providing that option.
