I would look into a car alarm system.
There are lots of options out there.
They usually have a main unit that you can accept inputs from:
Remote for (activation/deactivation of alarm) High Output multi-tone Sirens Dual Stage Shock Sensors
Motion Sensors
Glass Sensors
Door Sensors
Some can even notify you when the alarm has been tripped.
So if you stop at a restaurant, grocery store, or sight-seeing attraction
and someone backs into your trailer you will know.
Best thing they will run off your 12 volt trailer battery.
Good luck, and hope you never really need it.
