When we are preparing to leave, I run the front jacks up high before hitching and make sure to pull the drains and thoroughly flush. The galley tank doesn’t appear to have the same issues.
Maybe someone else has a better solution? I am hopeful 😊

My 22 3871RL has the same issue. I had the dealership check the tanks out and found no issues. He said the same thing about the tanks being level. I fill them before I empty and jack up the front end before I leave to ensure they are drained.
