I went this route on my last SOB travel trailer. It had two bathrooms, four tanks, four dump handles and two dump outlets (as well as two black tank flush connections.) Setting up was a lot of work, but I was able to leave both gray tanks open once I was connected.

If you're in this situation, I'd strongly suggest getting extra hoses so you can connect both at the same time. Switching it back and forth is miserable. I bought a telescoping hose storage tube and secured it to my square bumper. This effectively doubled my sewage hose capacity. I had a 15' and 10' Rhino hose in both the tube and the bumper and that worked for pretty much any connection I needed. Connect those to a Y connector and you're good to go.

But setup and breakdown is still a pain.

Enjoy your new rig and welcome to the forums!
