this is what I try to tell people will lots of 'stuff' and big racks on the
top of their vans.

one very fancy fan I work on...owner says he gets 14mpg.

that's a 3.0 six cylinder Tribecca EZ30 engine, Syncro Vanagon, not terribly
large or agressive tires..
but a big ole honkin' full lenght roof rack ( that's empty 11 1/2 months of
the year I believe ) plus a pretty big spare tire up there ..
by your calculations he's loosing out on  $ 500 in fuel costs a year likely.
He should be able to do 16 to 17 mpg.
it goes really well too of course.
