Hi Frank,
I wonder if you could install one of the Standard MaxAir vent cover?
You wouldn't have the same problem with the standard MaxAir vent cover because it doesn't have the over hang. I'm guessing it's the over hang that's getting in your way.
The standard one may not give you the same air flow that the other MaxAir vent will but I would think it still would do the job. The only thing that the Fantastic Fan manual says about vent covers is that they don't recomment any because they (as stated in their manual) "
greatly restricts airflow, causing accumulation of dust and increased sound levels."
I wonder if anyone else has installed the standard MaxAir vents over a Fantastic Fan. I would think there are, since I believe the Fantastic Fans have been out a lot longer than the MaxAir 800 Vent Cover.
It might be worth a post on RV.net Open Roads Forum to see if any has installed the standard MaxAir vent cover over a Fantastic Fan to see if it works ok.
Here's one post on the RV.net forum I found talking about using a standard MaxAir vent cover over Fantastic Fans, at least one person said he's using the standard MaxAir vent cover over a Fantastic Fan with no problems.

Look at the response from "tomousecap"
He made some minor modifications to the standard MaxAir vent cover by changing the mesh to a different screen to increase air flow.
Hope this helps.
