Schwans has been running propane since about 1980. Cost savings pays for the conversion in less than two years BUT they are a fleet running about 6500 trucks, most of them on propane. They are refueled at their own depots. They do not own the storage tanks and refueling equipment. That belongs to the company that provides the fuel. They purchase fuel on contract, 40 - 45 million gallons a year. As a result they are getting fuel delivered to their depots at a lower price than I can buy it for heating use, and their price includes the road use taxes. Because of the difference in weight of the fuel the LPG system and full tanks weigh about the same as a gasoline system with enough fuel to travel the same distance. A CNG fuel system filled to the same weight would only travel about half as far because of the heavier tanks required and CNG is not stored as a liquid, only under high pressure.
