Crews were dispatched to the fire just before 5:30 a.m., and they called for mutual aid shortly after arriving on the scene, fire officials said.They called for mutual aid out of caution since the propane tanks appeared to be leaking inside the garage and firefighters feared that the fire could spread to nearby garage and camper. As they worked to put out the blaze, firefighters safely removed the propane tanks from the garage. The fire did not spread to the garage, but the camper was destroyed, officials said.
