Anyone who pulls a trailer or an RV knows that a lot depends on keeping that hitch safe and secure. A trailer can be an easy mark for someone who is looking for a quick score; it doesn’t take much to lift it off the hitch and attach it to a second vehicle.

To prevent this, the use of a trailer hitch lock is vital. There are several different types of trailer hitch locks available, ranging from those that secure the hitch with the trailer attached, to those that prevent anyone with a key from hooking up to the trailer in the first place.
