Get your Rascal ready for the world's smallest caravan. The QTVan ($9,000) is designed to be towed by a mobility scooter and small enough to to be used on the pavement. It ain't no Airstream, but it does features amenities like a full-size bed, 19-inch LCD TV, radio, alarm clock, book shelves and kettle, perfect for roughing it on the corner of Elm and Green.
