We leave the gray water valve open all the time until the black tank is almost full. Then we close the gray tank valve and take a couple of showers to have gray water to flush the pipes and hose after dumping the black tank.

Depends. We typically leave grey closed unless both doing showers and will likely fill the tank, and when running the washing machine. We try to ensure we will have ample water to flush the hose after dumping black tank.

Both tanks are always closed. Leaving the grey open can result in sewer flies and a potential risk for sewer back up at the park. We pull the grey every morning since full timing for over a year now.
That's just how we roll.

Black shut, Grey open, unless we don't.

No rule and the best method is your method, the black tank needs to flush so fill it then pull seems to be the only standard.

I used to leave it opened (gray)until the day before we left and let it get full. Now I keep them both closed because, while leaving a park last summer I saw millions of little fly's, gnats? fly out after I pulled the drain line out of the ground. So that's why I keep mind shut, I don't want them in the MH. Yuck
