Curious about Car Camping not tent, my fault.

Does security check on car camping daily? I was curious about leaving our tent and canapé setup while we head into the festival. Concerned about people stealing the tent and or other items...? I have read most of people's camping experiences and would like to be prepared for anything.

To the group who had somebody get busy and leave a present in your tent, sorry to hear, that's fucked up.

Thanks for the feedback.
