I have a 2019 alpha wolf rk-l. having trouble with the main gray water tank. Specs show it has 84 gallons of grey. However I believe that is a total of both front and rear grey tanks. We seem to fill the main gray tank with only a couple good showers. This has the standard showerhead and when both of us take a shower the second person taking a shower will have the shower floor fill up an inch or more seems like the tank is full. I will open the main gray tank to drain and a lot comes out and the shower drain imediately. How fast does this gray tank fill with just a little bit of usage?
Yeah...84 is probably the combined cap of the two. Could be same size or one bigger and one smaller. Now your definition of a "Good" shower. How long for each of you ? Two long showers could be more than the tank can handle. Just speculating on your issue.
