How can you identify if your black tank 1 is for the main bath on a Momentum 31G?

I have 2 black tanks on my Momentum 31G. I Want to be able to identify which black tank is for which bathroom. Any ideas?
 
Empty them both, then fill one of them up and see which valve empties the tank.

The front black is for the main bath toilet only. 2nd black is for the sink and toilet in the garage half bath and the kitchen sink. Gray is for the shower and sink in the main bath.




 
Terry, where can I find diagrams like this for other models? I have a 2022 Reflection 324MBS and need to see where my pipe bends are. Any help would be greatly appreciated.
 
The diagram makes complete sense to me. I have ‘21 31g. I mostly use the main bathroom. I very rarely use the garage bathroom.

When I go to dump my tanks. I have 2x black handles and 1 gray.

My assumption is that the forward black handle which is next to gray is for the main bathroom. My other assumption is the other black handle is for the garage black tank.

However, I just dumped both black tanks. The forward handle seemed appropriate for the amount of use between dumps. However when I opened the rear black handle, it seemed that it was super full.

Am I missing something in terms of connections or plumbing? Or did I need to worry about a potential leak that is filling my rear black tank?

Appreciate the help!

The rear black tank is also for the kitchen sink.
 
Ahhh… thanks! I thought it went to the gray tank. That makes a lot more sense when I compare to usage.
