Travel trailer security - keep it or stuff from being stolen

The only thing I do is put the tongue latch back to the closed position and put my lock back through the hole to lock it. No fancy hitch lock. Everything else is left outside set up ready to use. Grill, chairs, hitch head (ball) is on the ground with a cable locking it to the A-frame and my equalizer bars are in a compartment. Never an issue. Relax and enjoy it.
