EarthRoamer XV-LTs are compact, energy efficient, solar powered luxury homes, built on a go-anywhere, four-wheel drive, Ford F-550 commercial duty truck chassis, and powered by a quiet, efficient and powerful turbo diesel engine. EarthRoamer XV-LTs are engineered for independent, standalone operation and are unlike any other vehicle in the marketplace. Unlike conventional RVs that depend on noisy generators and campground electrical connections for power, EarthRoamer Xpedition Vehicles use massive solar panel arrays, huge engine driven alternators and large battery banks to provide quiet and environmentally responsible power. EarthRoamer XV-LTs feature strong, lightweight, attractive, molded one-piece seamless composite bodies.
