If you have solar on your rig you could set up a laptop with a camera pointing down the middle and if you connect it to the Internet you can watch your RV from anywhere in the world. If someone breaks in call the police. You probably could wire it to some motion detector to send you a text alert and you have a DIY security system. You could even talk to the robbers if your speaker is on and suggest that they leave quickly before the police arrive. If I leave my alone for long periods of time I may do that. Bubba might even set up a gun with a remote control, but I wouldn't go that far. You'd probably get sued or arrested.
