No they don't. Spaceships don't have internal heating when the engine isn't running. There isn't an option for an auxiliary heater, gas or electric heating device. If you would like to add extra warmth during colder South Island winter nights then please add a Winter Warmer Pack.
Your Spaceship will keep you warm, even in winter. Our campervans are based on a car model (Toyota Estima). They have better insulation than a campervan that is based on a cargo van model.
And we have a range of optional accessories to keep you warm in winter and cool in summer.
