Here is our experience with 3 class A m-homes. I keep a log of fuel usage, and fuel mileage is averaged over several thousand miles for each. Fuel usage does include some generator run time:
33' gasser with 454 engine @ 16,000 lbs max - 8 mpg
35' gasser with V10 engine @ 22,000 lbs max - 7+ mgg
40' diesel with 400 HP Cat C9 @ 31,000 lbs max - 6.4 mpg
We may be a long way from guidance for the OP.
Pretty hard to compare an older (much lighter)coach with 5.9 liter Cummins B with a heavy 40' with 9 liter meeting much stiffer EPA requirements.
I promise you, a reasonably driven reasonably light coach with Cummins B can get 10 MPG on level and 9 in hills. Want to drive 70 MPH? NO WAY to get 10 MPG.
