A 1947 Kamp Master teardrop caravan is still being used. The model was produced by King's Trailer Company in Torrance, California, between 1947 and 1950. The body measures 8 feet (about 2.4 m) long and 6 feet (about 1.8 m) wide, with a dry weight of 840 to 870 pounds (about 381 to 395 kg). It features a pop-up roof, a kitchenette with a three-burner stove and icebox, and a slide-out sofa that converts into a double bed. The owner added a battery and a 5-pound (about 2.3 kg) propane tank. At auction, it could fetch at least €23,000.
