Fueling up for weekend when RV pulled up pump beside me. I noticed he had bungee cords around support arms and fasten to rail at top of awning. He stated that a tractor/trailer rig (two lane road) sucked the awning loose from rail early in the day, he was trying to get Nashville for repair. Anyone seen or heard of that before? He indicated that the incident was unnerving as I would think it would be.
