  • Question about tank capacities for a 2021 397TH

    Our 2021 397TH has two black tanks for a total capacity of 104 gallons, does anyone know if each tank is 52 gallons or the sizes of each tank? Also, we have two grey tanks for a total of 104 gallons, does anyone know if each tank is 52 gallons or the sizes of each tank?

    thanks

    Welcome to our owners technical forum. When you have a chance, have a look at our welcome post. https://gdrvowners.com/forum/main-fo...to-new-members . This will help you set up your signature and navigate the forum.

    From the information that Grand Design has provided to the moderators of this forum, all four of your holding tanks are the same. The Grand Design reference number is HT466 . . . unfortunately this does not cross reference to a drawing (that I can find) to confirm actual volume of this tank. You are probably close by dividing total volume by number of tanks.

    BTW . . . every tank installation will be slightly different depending on how the tank is supported and how the inlet and vent stacks are plumbed. It is a worthwhile exercise (at a full hook-up site) to measure how much water you can put into each tank before it backs up . . . for future reference.
