Update from RV Air about the filter:
Thank you for reaching out to us. I have had a conversation with someone else that had the same a/c unit and the filter measures 9” x 11.25”. I apologize, but currently we don’t have a filter that fits those dimensions.
If we develop a filter that fits that or develop something to would be able to trim down to that size, I will email you about it.
Safe Travels,
Ross
