Looking for end cap or valve for 2021 Roadtrek Zion macerator hose

[Chazy]

Greetings everyone. I just picked up my second Roadtrek, a low-mileage 2021 Zion SRT. The macerator hose on my first Roadtrek, a 2011 190 Popular, was equipped with a simple plastic end cap and ball cock valve, so when I stored the hose nothing could leak. The hose on my 2021 does not have an end cap or valve, so when I put the hose back into its storage compartment anything left in it will pour out--not a big deal yet as I just emptied some clean water but needless to say the black water drainage experience will be less pleasant. How have others on the Forum handled this? I have tried every search term I can imagine on Google and Amazon but no luck yet. Thank you!
