Thanks. We picked up one of those from Camping World on the way home from a trip and just quickly tried it on for size. It was not a good fit to put it mildly. I think the wooden base on the vent will have to be enlarged or something to make it work. We immediately knew it was more than we had experienced in the past and just returned it and figured someone here would give us guidance. You might want to send the previous owners of yours a thank you note ;-)
