What is the fuel economy, or UNeconomy, on a "C".

If MPG is a big concern, there are Sprinter diesels which can get upwards of 18 MPG. However, if given the choice between a Sprinter versus a Ford E-450 of the same floor plan, I'd go for the Ford, as the $15k difference in chassis would buy about 40,000 miles worth of gasoline. On a class B, it is a different story, since the whole B market is going through a major shakeup this and next year due to the new van chassis (Ford's Transit and the Fiat Ducato.)
