Did you ever had an idea to cpnverta small electric citv car to a camper vehicle? A New Zealander living in Slovakia did just that. He turned a tiny electric Peugeot iOn into a camper.
Of course, we are not talking about a full fleged camper van with a bed and all expected utilities - it's all about turning 166 litre luggague compartment of today already old EV car into a small kitchen. Even small as it is, it has all the utilities necessary to make a delicious meal: gas cooker, washing basin and even a fridge. And there was some room left for two cabinets to store cooking equipment. And there's also tha back seat left to store all the lahguage, tent and other necessary camping equipment.
So, if you have some artisan skills and free time, perhaps you can produce something similar in your garage.
