Here's my scientific answer for change in MPG based on roof raise height:
0'-1" to 1'-6" roof raise: no change.
1'-7" to 3'-0" raise: current mileage x .98, primarily because you're periodically idling the bus while answering questions about your exceptionally high roof raise.
Above 3'-0": Number of miles to the nearest overpass divided by the current gas tank contents, in gallons.
I'm basing the first number on the fact that my 10 MPG shuttle bus still is expected to get 10MPG towing a Ford F150.
