5.4L vs 6.8L in small Class C
We have been looking at Class C vehicles in the 24' range typically denoted as 22H, 23C, etc., we will not be towing a "toad". I see mostly units with the 6.8L V10 but occasionally one pops up with...

"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.)"
and you will have less power, they go hand in hand.
"Compare:
Ford 6.8 V10
2 valve version - old version
265 horsepower at 4,250 rpm
425 foot-pounds at 3,450 rpm"
Those are old numbers that only apply to the old V-10's. If your V-10 is 2006 (?) or newer you will have 305 Hp at 4250 and 420# of Torque at 3250 in a 2 valve. Mate this power package to the 5 speed Torque Shift trans (with full Tow Haul), and you will have plenty of power and 9 to 10 mpg in most Class C's (at least anything under 30').
Our 24' C cruises 60-62 at 2100 rpm, 6% grades are 55 - 60 at 3250 rpm (max torque) and once in a blue moon will it down shift to third and wind out to 4,000. We average 9.5 mpg consistently (and that includes some generator time).
As always... YMMV.
