Any automotive alarm company can install what you are looking for. They will be happy to do so as it is the same kind of alarm they normally install in a vehicle. Your park neighbors will likely be happier to see you leave if the alarm goes off while you are gone.

The RV alarms are easy to defeat sinece all you have to do is remove the power to the rig. Disconnecting the shore power cord and battery contacts are a snap especially if the battery acess is only secured by a single standard lock on the panel.
