Pisces, I've never had a problem with mine, but there is nothing of much value left behind, and I never lock it. The most valuable thing left in there would probably be the wood stove, but it's screwed down. My son's buddy has had his broken into on the same lake more than once, door ripped off, Mr. Heater stolen, assorted tackle. I guess if there's nothing to take, they should leave it alone. (But that's all wishful thinking)
