This old hill ground I own makes maneuvering my new (to me) trailer tough, so I've experimented with different spots on my 6A, trying to find a spot that's best for storage.The spot I like best is along my shop drive in a fairly level area unfortunately it's also close to the road, making it a target for thieves..... I have security cameras but I'd need to install another camera to shoot my shop drive to the street... What anti-theft devices are out there for trailers?
