Question on 303 waste water tanks

[ADT_48]

Hi - Does anyone know if Gray 1 is bathroom or is it kitchen? I read some where that the kitchen is 32 gallons and the bathroom is 43, can anyone confirm this?

Getting ready to head to Bristol for the NASCAR races this weekend and as all my camping to date has been at full hookup I am trying to plan my strategy for dry camping

Thanks!

Valterra makes a blade valve that goes between the rv dump pipe and the drain hose. You can leave it closed and open the grey water drains so the tanks equalize through the dump system.When you go to dump, attach the hose, close the grey water valves, open the blade valve then dump as you normally would.
