CNG/LPG capable engines are an option the new F250s, but it doesn't come with the injectors, lines, or tanks, so there's still work to be converted. I think the only people who will be using this are for delivery trucks and such, since I don't feel public LPG fueling stations are that common. I know there's a Schwans truck I've seen around once or twice running LPG, but that's about it.
