* On the way back home from the dealer in PA for a water-tank recall service, the right leaf spring on the trailer broke on the highway and caused the trailer on fire. The less than 3-years old trailer was totaled. Police and I took photos of the damaged trailer and spring. I also kept the broken spring for inspection. * It could be a FATAL incident. We were luckily stopped for gas otherwise the fire could be breaking out when we were driving on highway! * The spring was permanently broken and was confirmed by the police and towing/service center. * The trailer was inspected by police/fire department and Rossnagle's Service Center (police called). * There were NOT any warning lamps, messages or other symptoms of the problem prior to the failure. We didn't feel any abnormal behavior of the trailer until we stopped for gas when we saw the smoke start to come out. I don't know how long the trailer body had been sit in the moving tire before the fire started.
