The origins of the Polarvagnen AB company lie in the spring of 1964, when Håkan Wallin and Bertil Holmqvist began manufacturing caravans specialised for Nordic weather conditions in a barn in Junselevallen. In 1966, the factory premises were destroyed in a fire. After several stops, production finally ended up in Dorotea in 1968. The "Polarwagons" are still manufactured here today, with the polar bear designed by Ragnar Granqvist as their trademark. The company employs almost a hundred people. After the merger with the Finnish vehicle manufacturer Solifer, the company has been called SoliferPolar AB since 2004. The production of the Polar caravans remained in Dorotea.
