Eugene Braidel has lived since 2018 in a motorhome about 4 meters long that folds flat. He installed four flexible solar panels with a total capacity of up to 400 watts, each weighing less than 2 kg, and since September 2019 has visited 48 states and 284 national parks. Braidel notes that knee and back problems make him question how much longer he can continue the nomadic lifestyle.
