For personal safety keep a can of wasp spray inside your rig. It is much more effective than pepper spray as it will shoot a blinding spray directly at an intruders eyes from 20 feet away. You don't have to gEt close like you do with pepper spray. They will be temporarily blinded and crying for your help while you are calling the police. The other thing is, wasp spray is legal everywhere I know of, while pepper or bear spray may not be.
