The propane tank on our Class A has a door with a lock, so no reason not to lock yours.  That will keep the opportunist from taking your tanks, but not someone determined.
OP here
Yeah I think what happened is some kids that live next to the storage facility were messing around and just opened the compartments to see what it was. All other compartments were locked. I realize that a lock will only keep honest people honest.
The storage place has no issues with theft as the owners live on site and know who belongs there. There are multiple security cameras recording everything as well. 
In a previous storage place someone attempted to steal my awning (Multiple crews were removed) pried open the front compartment and took a bunch of beach stuff stored there and attempted to pry open the door. This happened in less than a week and my 5th wheel was out of there immediately.
