The vehicle was being towed by a Class A RV using a manufacturer approved towing system. All connections and safety measures were properly installed and tested just prior to incident. Vehicle has been towed using the same equipment for several years with no incident. The attachment from the frame to the front-end assembly completely separated and the vehicle body went into oncoming traffic. The vehicle in oncoming lane was struck and one individual injured. Upon visual examination, the frame component appears to have failed on both sides at the front-end. The bolts are still in-tack, tight and uncompromised. This is a frame component failure.
