Last winter a collegue of me offered to bring my cat to our company wharehouse for winter storage, and crached one hull into his car.
This spring a nice gentleman offered to help me park the trailer, and made a turn direct after disconnecting from the car, I ended up with a big dent in my 12 weeks old car .

The only plomblem I ever had while trailering was loosing a paddle on the highway (forgot to take it of the tram) no one got harmed .
