What lock not to use

To get my TT you will have to cut the lock off the tongue , move my truck , move my daughter in laws car , move my sons car and finally move my daily driver , by the time you do all that my neighbor being ex military sniper will most likely have a red dot on your head , not to mention I most likely will be home , best thing for your well being is go pick on someone that has one of those yellow tongue locks

I'd like to know what a good, top quality lock would be.

Like GordonThree said above, a cutting disc will get about anything off.

Maybe it is a matter of keeping honest people honest. Most of the time, I would assume that is used in a storage yard, or similar. Making your trailer a little more difficult to steal than the one next to you might be enough.

Any that rely on that design will have the same weakness.

Even a strong lock will not stand up to a cutting disc on a cordless grinder.

That's pathetic but what is a good hitch lock?

Good to know !
