Taking long trips can be good for your mind. Large camper trailers are not for everyone. The QTvan happens to be the world’s smallest caravan. It is small enough to be used on the pavement or even inside shops, and yet it still has enough space for a bed and a TV. The QTvan can go for up to 30 miles on a single charge. It has space for kettle and other necessities for your trip. How neat is that?
