We travel a lot with a trailer these days. I park in unknown locations with thousands of dollars worth of hunting gear in the back seat. Even if you lock the doors and hitch up, leaving your trailer in the parking lot and driving away is a little nerve-wracking. This shoe gives me the peace of mind I need. Just like door locks, nothing will stop a determined cheater from escaping with your belongings, but it will definitely slow them down. It is lightweight and easy to put on and take off. I seriously don't see a trailer being towed anywhere with the trunk. It's very noticeable, which is probably the number one security feature.
