I planned everything to be modular:
While camping you take the back seats out and are left with two seats and a camping mobile.
You can leave the back seats in the car and install the kitchen box and you have your kitchen with you if you want to go climbing with your friends.
Or you take both boxes out and your car is a normal mini van again.
The main goal was to build a small camper that is very fast and easy to put into a sleeping position."
