Yes, Airstreams get stolen regularly .. even right out of supposedly "secure" RV storage lots!
And here's the bottom line: Most hitch locks are really worthless.
I know, those are harsh words, but it is reality. If you spent $30-60 on a hitch lock, you probably got about that much protection.
If you want to see virtually every type of hitch lock being defeated, just watch the video below. But fair warning: you'll be horrified to how little protection you really have.
There's only one type of lock we would trust on our Airstreams: the Megahitch Lock "Coupler Vault" PRO. It's the latest generation of the toughest lock we have ever seen. Considering the value of your Airstream, it's really a no-brainer.
The PRO is improved over the previous version in several ways:
We offer the Megahitch Lock in silver/gray to match your Airstream. Just order the size you need: Late model Airstreams take a 2-5/16" ball, while many vintage Airstreams need a 2" ball. The Megahitch Lock can also be configured to fit both sizes!
Installation is easy, requiring no tools. Comes with two keys. This excellent lock is made in the USA.
Note: because it requires access to the hitch coupler on your Airstream, this lock won't fit on trailers with Hensley or Pro-Pride hitches, unless you first remove the hitch head.
