This retro-style trailer weighs just 1,100 pounds, so your favorite camper or Airstream aficionado can tow it with most cars for camping trips and cross-country adventures. The HC1 features a modular interior that can be arranged into various modes, from a sleeping space for five to a mobile office to a living space with a kitchenette. The base model comes with two AC wall plugs, dimmable switch lighting, and seven storage shelves, among other features, and you can shell out for extras such as a stove top, an air conditioner, a 100-watt solar panel with a charger and inverter, and a solar-heated shower.
