I just picked up a small utility trailer, 4x6, over the weekend. Unfortunately, I don't really have anywhere to store it, other than my garage, which means I need to park outside. For a small trailer like this, what would be the best way to secure it outdoors? I realize that if someone really wants it, they are going to get it one way or another. I'd at least like a pretty solid way to deter someone from putting forth a lot of effort to snag it.
