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".
Now factor in the savings from not using propane to cool fridge and it makes it CLOSE to a wash
