Replacement Locks for Under-Coach Storage Compartments

I assume that somebody with that attitude doesn't lock their S&Bs front door when they go on the road?
I think that a ragamuffin strolling thru the campground looking for an easy mark would first spot compartments locked with the old 751 special and ignore a harder target. Or better yet compartments with no lock at all.
now if you are talking about parking out in the boonies a zillion miles from nowhere, then chain saws, plasma cutters, and pry bars come into play.
