Any recommendation on any trailer security devices? the Trailer Keeper seems interesting. I had the master lock set before and it seemed OK, but it doesn't disable the tires.

You might do a search on trailer locks. I think I remember a thread about that not long ago.

This gets discussed all the time so there are plenty of searchable threads. I use 4 kryptonite cables thru the wheels and a hitch coupler block lock.

They're nothing but a dissuasion to a thief. I just don't want some goofball hooking up and rolling away because it's easy. A pro could ber rolling in 5 minutes with what I have on there.

I'd like to find one of those GPS trackers that had an automatic calling feature when someone messed with it.

I also have all the locks available... spear, coupler, hitch, etc, etc.... But like you said, a GPS device would be nice. I can only picture taking an R22 and meet the suckers....
