The rear awning comes free with almost all Spaceships campervans in New Zealand (only the Dream Sleeper Mini range doesn't come with a rear awning due to the different set-up of that campervan model).
The rear awning is a tent-like construction that will cover the back of the vehicle. It's the second sleeping option of your Spaceship: partially extended outward. It's a great solution on those warm New Zealand nights to get some extra ventilation or airflow. It also creates more space as the bed will be partially pushed outward and covered by the rear awning. That means more space inside the campervan at night, making it even easier to move around and to set up the bed.
Setting up the rear awning is super easy. Simply pull out the extension bars at the back of the vehicle. The same bars you use to create the cooking area at the back. Put the board and the mattress on the bars and set up the rear awning. See for more info about the rear awning and how to set it up.
