Developed by ETA (Environmental Transport Association) the QTvan is the world’s smallest caravan and is so named because it caters to three peculiarly British obsessions: queuing, tea and caravans. QTvan for people who use a mobility scooter without breakdown cover and face the prospect of a very long wait should they suffer a mechanical fault or their battery runs flat. It is best-suited to local trips of up to 10 miles.

Eco rating: The QTvan is the world’s most environmentally-friendly caravan.
