Flagstaff Fire crews tended to a motorhome fire in the Country Club neighborhood of Flagstaff Sunday night. Crews responded to a report of the fire at around 9 p.m. When the first crews arrived, they saw an RV fully engulfed in flames. Fire was starting to move to the adjacent home. Firefighters attacked the fire aggressively and quickly received help from other crews. The swift response quickly extinguished the RV fire and saved the home from catching fire and causing extensive damage. Crews remained on the scene for an extended period of time to ensure the RV was fully extinguished. They also worked with utility companies to make sure the scene was safe. The cause of the fire is under investigation and has not yet been determined.
