I will be sometime before "real world" fuel economy numbers come in, but I will bet that the V8 gets at least 10% (probably more) better fuel economy simply because there is less internal friction (fewer bearing journals, fewer piston rings, etc)
I'll lay money on the fact that the new 10 speed will be in the motorhome chassis by 2021MY !
The new F-53 will only have the 6 speed and I don't see it being in the future.
Also posted on a video from YouTube testing the 7.3 with a 10 speed pulling a load it never got past 8th gear, so having a 10 speed on a heavy motorhome means it wont get to over drive, less gears means less friction as well.
And I will bet a hundred it wont get any better mpg..
10 percent is dreaming..
