It wasn't the fuel mileage that led me to the Navion (Sprinter chassis, made by Itasca/Winnebago) but the driving comfort - much more legroom in the Sprinter based units, no "doghouse" for the engine. The Sprinter units are also a foot narrower than the Ford ones, advantage or disadvantage depending on your preferences. The difference in fuel cost is pretty much negligible as "Jayco-noslide" pointed out.
x2 on the driving comfort.
On narrow roads I'm really glad to have the narrower body. Once parked, I'd of course rather have the extra interior space.
