I could get that off pretty quick It's really just a version of the municipal boot used by some cities. The thing that makes them work is that they have your license plate number and if you cut it off they make you pay for it in addition to fines. I suppose it could make the thieves move onto the next target, like an alarm does, but not if they want YOUR trailer. I use a homemade tongue lock and always try to block it in with a car or truck for extra insurance.
