In the end, it all depends on what you need the lock for: Towing or sitting. So, your choice of lock will be between receiver hitch, coupler, and chock lock. We have explained the matter further, below.
1. Receiver Hitch Locks- The receiver hitch lock is what you will use while towing. These locks work to connect into a hole which is located on a receiver. The receiver is connected to the vehicle doing the towing. Receiver hitch locks will secure what you are towing into the hitch. No separation will occur unless it is unlocked using a number combination mechanism or a key.
2. Coupler Locks- Coupler locks are different from the trailer hitch locks, in that the coupler lock secures your camper, boat, RV or trailer when it is not being towed. They will be crafted in a ‘U’ shape and are designed to fit over the coupler on the trailers tongue. Using a coupler lock will prevent anyone from backing up, and hooking their vehicle up to your trailer and hauling it off.
3. Chock Locks- Anyone who lives in the city is familiar with ‘boots’ which are attached to a vehicles tires to prevent it from moving. The chock lock has the same function. These locks are designed to fit over the wheel of your trailer, camper, RV to prevent it from being hauled away by a thief. The value of these locks is that they provide a visible deterrent that can be seen a ways off.
4. Buy the Proper Fit for Your Needs- Finally, your lock will not be of much use if you do not size it properly. Your trailer hitch lock must be chosen based on what you will be towing. For example, a Class I can pull about 2,000 pounds and a Class V can haul 12,000 pounds plus. So if you have a heavy load to tow, choosing a Class I can lead to major problems or even an accident. Know the weight of your load before you begin to shop for your trailer lock.
- Class I: 2000 lbs
- Class II: 3500 lbs
- Class III: 6000 lbs
- Class IV: 10,000 lbs
- Class V: 12,000 lbs.
