I'm an EV analyst focused on a real-world, objective take on electric vehicle ownership. I've been driving EVs for over a decade and have owned 8 across multiple brands, with seat time in many more. EV Outdoors is independent analysis of EV towing, road-tripping, and the realities manufacturers leave out of the brochure.
