Editor's Pick: When your trailer or RV is parked at a campsite or in the driveway, just insert this lock to deter theft. The lock head rotates to fit different hitch angles, making it more secure than a standard pin. It has a weather-resistant coating, so it won't rust or seize up in the rain. When not in use, toss it in your toolbox and grab it when needed.
