we kept our bunk end fan/light combo from our 2011 popup when we traded it in thinking to use in our 2016 hybrid. nope, sometime between 2011 and 2016 - they changed the fans to the smaller plug.
I have not seen an adaptor but i think this may be the base if you want to switch it out (etrailer) ?? not sure how easy that would be - but just a thought.
