My coach automatically dumps the suspension air when the Autolevel button is activated, but if you have a manual dump switch, the choice is yours. Dumping air gets the coach body lower and make entry and exit easier. That's all.
But there is no need to be concerned about protecting the air bags when leveling. The system is designed to be deflated and inflated, and nothing is going to break or wear out prematurely.
