Just posted a write-up on the mod I did to connect the kitchen/galley tank drain to the front bathroom drain, as promised last week.
8281WS Sewer Mod - Connecting Galley drain to Front Drain
Hope it's useful to someone.
Also hooked up the mount I bought from Amazon for attaching my Furrion back-up/observation camera monitor to the rearview mirror.

I found the original suction-cup to be unreliable, occasionally falling off.
I did start designing my own mount, to get 3D-printed, but knew that I wouldn't have time to get it completed before our next trip, so found this one.
I'm pretty happy with it so far. I've set it to only partially block the rear-view mirror, while not encroaching too much on the forward view.
At first I had the clamp blocking the light sensor on the mirror, thus causing the mirror to be permanently dimmed, but I moved it a little, and it's in a good spot now.
