Query: hefty but not so theft proof

I purchased one of these for my enclosed quad trailer. While at the dunes, I absent mindedly locked my keys inside the trailer. Two hits with a standard sized claw hammer and the lock-clench mechanism broke and the lock fell to the sand. TWO claw hammer hits from a thief taking whats in my trailer.... thats about $25000 worth of UTV's and quads. If I still owned this lock, I would grab a claw hammer and re-prove to myself that I need something better.
