Coupler lock

Got this heavy duty lock from Proven Industries. Should slow down a trailer thief.

I got the same one. Pretty sturdy. I tied the chains to the lock with a Master Lock.

Not really. Just back up to it hoist with chains thru the A frame and go.

You take all the fun out of it

Josh is right of course. That said that looks well designed and heck you really can't go too far too fast with a trailer suspended by chains whacking into the thief's bumper so yes it's a good idea.

Anyone have experience with this lock. The master lock is not necessary , it’s leftover hardware.

[Rocinante]

Yes, we have that one. It’s called a “California Immobilizer.” Easy to use, seems quite tough. We also run a very large, intimidating, Master Lock padlock through the chains, making them useless. I don’t have to make the trailer theft-proof, I just have to make it more of a pain in the neck to steal our trailer than it is to steal a different one. Similar to the theory about outrunning a bear. I just have to outrun the other guy, not the bear.

An experienced RV thief can tow it away very easily with the chains, or bring their own chains.... A sloppy setup, but it could be moved..

[Rocinante]

See, if y’all buy that and either do nothing or go out and buy heavy cut-proof chains and run them through your wheels, and heavy boots that make the trailer particularly difficult to drag away, our position is just right. We’re between the two. Most folks do nearly nothing, which is fine by us. A few folks go all-in, but very few indeed. So, our trailer is more of a pain to steal than most. I’m busy outrunning those folks who don’t really even try, while others encourage either that behavior or an extremely inconvenient approach by insisting that the only way to win is to outrun the bear. That’s fine by me.

I have the Proven Industries. Yeah, a tow truck could tow it away, but it's stored in a gated secure facility.
If it becomes such a nightmare to secure one's valuables, I'll just stay home, I hope that day never comes.

BTW, my one criticism of the Proven Industries (besides the cost) is how hard it is to insert the key to open the lock. I think I need a mirror to see which way the slot is oriented.

Special Thanks Rocinante, Johnyooo, Mollysdad,
I agree any roadblocks to a thief helps. The professional is tougher to deter. I am going to add a strong lock to the chains so they are not as easy to form a cradle. I may look into a wheel lock for my comfort.

Store the rubber tires with wheels elsewhere when stored. That could be the ultimate inconvenience for all concerned.....
