I leave mine on all the time. My Jeep has been broken into a few times at work. Not that I'm complaining but, they always left the d-rings and Rigids alone :idontknow:. Could be that I work near Detroit and they don't have a clue what to do with them.
My house is in a very nice/upscale area and if it doesn't consist of a catching buzz, most kids don't want anything to do with it around here. Mommy and Daddy buy them everything else. So I don't worry about much, just remember to bring the cooler in at night!!
