from what I hear from others it is hit and miss. all you can hope for is a tall fence and a junk yard dog to take care of things. I hear several times on here that TT's are broken into and tv's are stolen. best to take every thing and every thing out of it, including the batteries, propane tanks, tv and leave nothing in the TT and I mean nothing. I know lots of people here in my little town who have parked next to their homes that are broken into. I know I don't sound too up beat about it but the thieves will steal your teeth out of your mouth while you sleep
