Let me tell you a story…
A long time ago in a galaxy far, far away (A couple of decades ago, in New Orleans) I had a neighbor, who was very proud of his brand-spanking new imported sports car. He installed the very best alarm in it, and made a point of testing the alarm where everyone in the neighborhood could hear it.
Fast-forward a couple of weeks. One of the neighborhood miscreants decided that such a fine automobile must contain goodies worth stealing. Unlike many miscreants who tend to be less than brilliant, and somewhat thuggish, this one was really quite clever. He swatted the sports car's windshield with a tolled-up newspaper to make the alarm go off. Then he ran and hid, and waited for the owner to come out to check on the car and rest the alarm. A few minutes later, he did it again. And again. And again. Eventually, the owner got tired of resetting the alarm. And all of the neighbors, myself included, got tired of looking to see what all of the commotion was. The next time the alarm went off, the miscreant broke into the car— while the alarm was blaring loudly— and stole everything of value from inside. Once the alarm quit blaring loudly all on its own in a few minutes, the miscreant even stole the alarm system!
The owner of the no-longer-beautiful sports car was terribly embarrassed when he filed a police report the next morning, and reported that his alarm system was stolen. The miscreant was never caught, but he must have achieved much street cred for sheer chutzpah
The moral of the story is, an alarm system is not
there to scare off a thief. It's there to let you
know there's something wrong, so that you can check on it. So, unless you plan to check on the trailer every
time the alarm goes off, there's not much point having the alarm.
Unless installing the alarm gets you a lower insurance premium, and the amount you save on the premium is enough to pay for the alarm, it may not be worth the hassle of finding one and installing it, and recharging your house batteries more often to keep it powered up.
I do have an alarm on my Airstream Interstate. And every single time the alarm goes off, I run out to see what set off the alarm. Doesn't matter if it's the middle of the night, or the middle of a thunderstorm. If the alarm goes off, I go look. Period.
