Thanks for your replies so far. Yes, I know I'd have to bolt the safe to a wall. I'm actually considering fastening anchor bolts to a concrete block wall with epoxy and then securing the safe to that wall with nuts through the inside on the back. These two safes are heavy enough so it would take a couple guys to carry one out. My neighborhood is pretty good though. I live next door to a K-9 cop who parks his squad car in his driveway and his dog lives in his back yard. And our schnauzers are certain to make a lot of noise.
