Camp Kitchen with Sink that connects to outside shower?

My low point drain valves are under the kitchen sink. With open end tubing under the trailer. I added fittings and valves to the tubing ends to allow me to connect outside for hot and cold running water. All I have to do is connect to the tubing and open low point drain valves for hot and cold water. I can connect to a laundry sink with faucet set up outside. Then connect an old hose I use for gray water dumping to the drain and run it to my 26 gallon tote or run it off into the woods.

I have a camp kitchen table with sink I use for tent camping with an on demand water heater. I can also connect the drain to my tote or run it off into the woods.
