Ready 4 full timing, but theft has me worried the most!

We have been fulltiming (truly, driving, camping, moving, camping, moving, etc.) for 18 years and we have never had anything stolen or been in a place where I was concerned about having anything stolen. The only exception I can think of was while at Huntington Beach, CA, parked on the edge of the beach and left a couple of folding chairs out while we were gone. The couple next door thought someone was "eyeing" the chairs and collected them up and returned them to us when we returned. Nice group of folks out here!
