Proven Industries Model 2517-AS Trailer Lock, Fits (2020-2023) 2 5/16-Inch Airstream Couplers, Made in The USA (Blue)

This thing, I hope, is fool proof. Wish the key was on the side instead of down. I have had it for a couple of weeks and my RV has not been stolen yet.

Excellent product and keeps us safe at storage and at campsites.

Great piece to equipment to keep my $78K Airstream trailer from being stolen.

Sturdy lock for my needs - my second from this company - made in USA.

Secures entire hitch ball assembly. Pricey, but so is the cost of a stolen Airstream. Hoped it would secure safety chain hooks but no, they’re too thick.

Someone will have to really work to steal my Airstream

Built by Brinks, if someone steals your trailer with this 50lb hunk of steal latched on it let them have it because they are one bad mother and you dont want to mess with them. Its so overkill its like wearing full body armor to a water gun fight.

Works great. The videos on the web site show fitting the safety chains in the lock as well. I tried about every combination and watched the videos several times and still no luck, the hooks are just a little too think. Maybe if the assembly that hitched in had another 1/4 inch of clearance.

Best lock on the market and American made

This is the best lock housing for a hitch coupler out there at this time. This is for my 1985 Airstream Sovereign (Remod) and it is an absolute beast. It’s expensive. But a missing trailer is worse and more expensive. The heart ache alone is worth the money. Get a GOOD puck lock and do your research since there are many choices and all have their vulnerabilities. YouTube has many videos of locks failing so you can make a wise choice. This model of coupler lock will NOT store your safety chains. And this is a problem since some thefts have occurred by the thieves hooking up the chains only and driving off with the trailer. But this gets harder to do the larger the trailer. Look into adding an internal GPS tracker so should your trailer wander off on its own you can send the police to its exact location. This too in my opinion is worth it in peace of mind. In a nutshell, I am very happy with this lock and do not believe a better choice exists. Buy this. Now go get a really good puck lock. And a GPS tracker. And maybe a HD padlock for the safety chains. Or make the chains removable. Some have added a wheel lock. Thieves are expensive.... :(
