I don't know if it is a no-no, but I have done it without an issue. If your regulator has a tank selector, just make sure the selector points to the tank that is still connected
๐Two seasons ago, our 20# tank that we use for our bbq grill and portable 2 burner stove went empty with a week left in the season. I didn't want to have it filled and let it sit all winter long, so I just removed one of the 30# tanks from the tongue and used it for the rest of the season.
