Dometic Roof vent lid

[Pantone 453]

Dometic Roof vent: Is it the same as a Fantastic fan lid? https://www.amazon.com/fantastic-vent-cover/s?k=fantastic+vent+cover​

I am looking to get a spare. Is it one size fits all? It appears that my fantastic fan lid and my normal (no fan) lid are the same.

Dometic now owns Fantastic, so I suspect there is a good chance it’s a fit. Send Dometic an inquiry to double check. A local RV repair shop might also be a good place to check.
