Another factor regarding any RV besides weight is the wind resistance; it takes more power for a box to cut thru the wind. Furthermore, due to the wind resistance most MH are hard pressed to get more than 10MPG, regardless of the motor.
Totally agree, the Class C with bunk over cabs will all have this huge constant that will vary little from one coach to another.
The variables would be total the mass and the available power.
Sounds like the 6.8L is the powerplant of choice.
My original post was intended to determine the viability of a small Class C equipped with a 5.4L, for example if a super nice coach popped up for a great price is it worth a look see.
I still wonder if 2 identical coaches differing only in engines would get the same MPG over a given route.
Would the 5.4L get better mpg because it is smaller of would it get worse MPG because it is running harder.
It might depend upon the terrain as well, ie smaller might be better on level ground but worse on grades.
