the sprinters going to win hands down for FE no doubt about it i have heard first hand reports of them getting 30mpg hiway out of the sprinters.. thats phenomenal for a full size van!
Not to mention you could go with biodiesel and go really green
I did ride in one that was kind of a mini bus.. decked out for a hotel transport vehical, it was a very comfortable ride more car like than a van , the diesel was super quiet also didnt sound like a truck.. very comfortable ride and was very quite like a car...
I own a e-350 diesel and it only gets about 18mpg.. it had gears for hauling heavy loads.. my e-150 302 v8 gasser got about the same for MPG's but is geared for a passenger van.
