In the seven years since I built my teardrop I have pulled it probably 50K miles and slept in it close to 200 nights. That's many nights in campgrounds and many more in remote locations. When I am away from the trailer for any length of time I put a coupler lock on. Even then if a thief wants your rig, he'll figure out a way to get it. Just go camping, enjoy yourself and if the area doesn't feel safe, MOVE! These things have wheels for a reason.
