From a Curbed.com online review:
The RV industry has been slow to adopt electric technology, and the innovations that have occurred are stemming from Europe. In recent years we’ve seen a few eco-friendly concept RVs, like an RV covered in solar panels or a travel trailer that can be towed by an electric car. Most recently, a German company debuted the world’s first manufactured electric camper with a decent range of 249 miles. In the U.S., however, the closest thing to an electric camper is the yet to be produced Rivian truck that features a kitchen and tent for overland camping.
Although years behind the auto industry, the RV industry is finally making making strides in efficiency and green technology. In the latest eco-friendly news, Winnebago Industries has announced that they will help fund the expansion of Motiv Power Systems, a provider of all electric commercial chassis.
