My 2019 330RL Laredo has two grey tanks and two separate drains. I joined the two tanks together, span was only four foot. I added valves as well. I tested both tanks and found galley tank held 24.6 gallons and shower/vanity tank held 25 gallons. A far cry from the specs Keystone claims to have 63 total grey water capacity. Good news is both tanks at same level so I can open both and level off grey water. Just some information for those that might need it. Thanks to all of you.
