Depends on what you want.
No gas RV will be great on MPG.... (if you want better gas mileage, the Chevy seems to be about 1-2 MPG better.)
Compare:
Ford 6.8 V10
2 valve version - old version
265 horsepower at 4,250 rpm
425 foot-pounds at 3,450 rpm
3valve version V10 - new version - only one availabe
Horsepower (SAE net) 362 @ 4750 rpm
Torque 457 lb.-ft. @ 3250 rpm
Ford 5.4 V8
5.4L (330 CID)
Horsepower (SAE net) 255 @ 4500 rpm
Torque 350 lb.-ft. @ 2500 rpm...
The three-valve version is not available in the E series chassis (be it a regular cargo/passenger van or a cutaway chassis for a class C motorhome or whatever) due to space limitations—the three valve heads are taller than the two valve heads, and the chassis doesn't have clearance for them. The two-valve version is not currently available on class A motorhomes (and probably most or all truck chassis models), as I understand things.
