Lightship RV has developed a new RV travel trailer that comes with the ability to propel itself while being towed, thus preserving either the range of an EV or the fuel economy of a gas vehicle that's towing it. Combining an ultra aerodynamic design with an electric power plant and 80 kWh battery pack, the Lightship L1 effectively solves the problem that EVs have with towing: the tremendous drop in range they experience. According to the company, this means "a 300-mile range electric vehicle (EV) used to tow it remains a 300-mile range EV, and a 25-mpg gas truck remains a 25-mpg gas truck."
