I am 75 and have been camping since I was a wee lad, back then stealing someone's camping equipment was thought of like stealing a horse in the old west. Things have changed, in 15 years of full time RVing we have had a couple of neighbor's trailers broken into, and a few years ago it seemed like every cooler left outside went missing, kids looking for beer I guess. And I heard of an elderly couple being murdered in their RV while camping near Flagstaff, AZ several years ago, so we all need to be careful, I carry a gun for protection, and when ever we leave the popup the gun, camera, and laptop, if we have it with us, always come with us. We don't really worry about the other stuff in the pup, and I put a Reese lock on the coupler so that someone can't just hook up the trailer and drive away. Security at the campground is something to think about, but don't let the worry spoil your camping.
