I have some very rural property in central Texas where I have a private range and where I plan to build a house someday soon. I need a place out there to store things that's secure and out of the elements, but I cannot afford to have something like a metal building built. I was considering purchasing a used 20'x8' standard shipping/CONEX container, having it delivered out there and using it as extra storage space for tools, etc I might use out there (also some SHTF supplies as well). These containers can be bought anywhere from $1500-$2500 with various charges for delivery depending on where its coming from, so I figure its a pretty good deal. I have liability insurance on the property, but since its unimproved property, my insurance agent claims there's no way to get theft/fire insurance on contents items out there and that my homeowners insurance for my home that's nowhere near this property would not extend to it.
This will be going to my place WAY out in the boonies off a long dead end dirt road behind two chained/locked gates and is not visible from the road. However, my neighbor does tend to hire illegals now and then to do work on his property and where I plan to put the container is definitely visible from there. I can throw camo netting over it or something, but theres noplace thats accessible by a delivery truck that will be out of the way enough such that its not visible from my neighbors property. Now I know these things are for the most part air and water tight and they have a small flipover hasp to accommodate a standard padlock, but I need something thats a little more difficult to defeat. One guy who sells these things offers what he calls a "steel lockbox" which is essentially a steel box with the bottom end opened welded over the hasp on the door such that it can only be accessed from the bottom, but this limits me to locks that use a key from the bottom (the hard-to-cut discus and puck locks have their key access from the side) and I'm not sure how it works when there are TWO doors on a container (two boxes?). Anyway, he wants $100 to add this to the box, but I'm not so sure its worth it.
Another thing I've seen is something like this: http://www.snatchlatch.com
. This is actually made by a local guy and is meant for locking enclosed trailers, but they mention something about shipping containers. Again, I'm unsure how well this would work.
I'm curious if something like this would be best:http://citywidesecurity.stores.yahoo.net/muhaforhopul.html
Some kind of round puck lock with a round shrouded hasp that has no access whatsoever for bolt cutters, but I don't know how securely it could be attached to a shipping container door. Would it have to be welded? What could I do to discourage someone from using a cutting torch? Maybe put bluff signs on the outside saying that it contains chemicals, explosives or black powder (some have questioned the legality of this, but Im pretty sure this falls under protected speech, especially since its on my own private property)?
Since its so far out and well hidden, a thief that knew about the place could have lots of private time to get at the stuff and I know that if they are really determined to get in, they will get in. I just want to make sure its as difficult as possible for them to discourage the attempt.
What other options do I have for securing one of these? Any ideas?
