    2021 303rls questions

    just bought new 5ver 303rls but was told 87 gallon grey water capacity but noticed 2 valves doesn't that mean 2 tanks, if so how many gallons per tank, guessing kitchen and shower +sink

    See this thread (post #10 and my post #18 ) where this was brought up a little over a year ago as well. The kitchen grey is 47 and the bathroom shower and sink is 40 for both 303s and 337s built in the last few years.
