correct thing to do is purge tanks of moisture daily when driving .
I would say every time you stop to camp would be best .
And by drain I mean pull the cord till moisture is expelled .
any air newer system have dryers that work quite well but it never hurts to check them if its easy .
BY the way these dryers need serviced once a year
