Our Airstream Interstate Grand Tour EXT Twin is in excellent condition. She has served us well, but we have decided to go a different direction in our travels. All standard equipment (including generator and solar), unmodified other than an upgraded in-dash stereo/navigation system that has wireless Apple CarPlay. Tires and brakes are recent, all service is up to date. Recent Lifeline AGM Batteries. Please reach out for more details or additional photographs.
