    The info available to me is dated and with all the variances these days in the builds it's probably wrong, but here's what I think I know.

    Bathroom Grey (their spelling, not mine): 43G
    Black: 43G
    Kitchen Grey: 32G
    Fresh Water: 74G

    The best way to determine real-world capacities is to hook up a water meter to the city water inlet and fill each tank until it is obviously full.

      Don’t forget to switch the meter from liters to gallons, when/if applicable.

          The kitchen grey is 47 and the bathroom shower and sink is 40 for both 303s and 337s built in the last few years. I suspect this also applies to some other models with 87 grey capacities but we would need to verify those. This has been shared here on another thread which I did not take time to find.

                If Im in a long stay I will common the two tanks together, seems like the bathroom would be 47 gall. I just keep a close eye on them and days left when dry camping. Easy to close off the valve I installed and open both tanks to get me through.
