Lost the water fill tank cap on the Kamparoo, where to find another one?

Let me know if anyone got any ideas. I wonder if a local a boat or RV place have such a thing? You can see the white cap in the attached pic, stolen from a for sale thread. My cap was black but the same identical version.

I looked on Ebay and West Marine and their caps is a different config than mine from what I can tell from the pics.
