Funmit Trailer Lock Universal Coupler Ball Lock Fits 1-7/8", 2", and 2-5/16" Couplers, Boat Camper Accessories for Travel Trailers Adjustable Heavy-Duty Steel Hitch Lock Yellow

This RV trailer hitch lock is fantastic! It’s easy to put on and take off, fits our RV perfectly, and feels built tough. I love that it looks great without being bulky or heavy. A solid choice for keeping your RV secure! Easy to take off even after it’s been on awhile. Functions nicely!

These are the cheaper version of trailer locks, I have 2 trailers and 1 on each of them, they work good for me, no problems.

This lock has exceeded my expectations. The lock is incredibly sturdy and easy to install, providing a high level of security for my trailer. I feel much more at ease knowing that my trailer is protected against theft. The durable construction and weather-resistant materials ensure that it will last for years. I recommend this trailer coupler.

Works good. Don't know about durability only time will tell. Only had a few weeks but seems good quality and finish

Solidly built and comes with 2 keys in case you lose one. You could definitely cut through this with a grinder, but it is a deterrent and that's what I needed.

I like the fact, I can lock it up and not have to worry about my boat or camper getting stolen

Works great.

Too light of build quality compared to others. On blow with a hammer and the casting would break. Psychological deterrent.
