All in all I feel the economic part is close to a wash but the convenience and comfort level is much greater.
A typical dash air system takes maybe (on average overall) 2hp, on an engine making 200hp, that is a 1% increase in load, therefore an increase in fuel consumption of 1%.
At 8.5mpg and 55mph that equates to 6.47 gal. / hour. A generator burning 0.5 gal. / hour would then be an increase of 7.7% in fuel consumption.
That's the equivalent of your mileage dropping from 8.5mpg to 7.9mpg.
I'd hardly call that "a wash".
