In a case of odd timing, I received mine yesterday, too. Just a day after I finish my bathroom fixture replacement...
I now have one of each style. If anyone has or will be getting a High Sierra shower head to replace the original Oliver pull-out faucet head (just the head, not the hose or entire faucet) let me know, and you can have either of mine free. The adapter with a male hose connection is for Oliver Travel Trailers pre-2021 and the adapter with a female hose connection is for the later model. I can bring them in April to the rally, I'll be at the Eggs-n-S'mores rally in Florida in January, or you can pay to have one shipped to you.
