The grey for the bath sink and shower share a drain port with the black tank but there are separate valves.
Every camper is plumbed somewhat differently so they do not all drain the same.

X2, almost, our outside kitchen sink drains into one grey and the inside kitchen sink, bathroom sink and shower drain into the other grey tank. 2 separate valves, wish they were plumbed together from the factory so there was only one valve, that way we would have a lot more usable grey water storage...

The guy that designed that plumbing never used an RV. I have 2 gray tanks, 1 for the bathroom and 1 for the kitchen. One of the items on my list always is NO outside kitchen, once was enough.

My trailer has 2 gray tanks and one black. There is a unique dump valve for each of the 3 tanks. There is only one dump outlet which handles all three tanks.

Not all are like this. When we were shopping for our Mini Lite, I saw some with a gray and black that both go to one dump outlet, and then a 2nd gray that has it's own outlet. The specific one I saw had a slide stuck out in between; I knew it wasn't something I was going to like. And since one outlet was in front of the axles and the other one was behind the axles, I didn't see that they could be hard-piped together very well.

So you need to understand exactly what you are getting or have.
