Based on my experience over on another forum, I think LisaPalmer is a spammer.

Another idea that is not an alarm, but may be beneficial, is the use of trail cameras (also referred to as game cameras) that are set up outside. They work off of motion sensing and take pictures of anyone moving around the RV (or home). A couple here in Oklahoma had a near home invasion and they are using the photos from a game camera that was attached to a tree in the front yard that got some photos of the perpetrators.

If one does this, just make sure to put the camera at a good height so that the criminals don't steal the camera. Some of those are even have "tree patterns" on the to blend in with the trees.
