Travel trailer security - keep it or stuff from being stolen

I am with the group that locks the TT and does not worry. The only things of values are the world's cheapest television and microwave. My camera, phone and electronics are usually with me. I suppose they could also take the four year old battery.

We have never had an issue with theft of the stuff we leave out of doors, that would mean another trip to the resale shops.

The lock through the ball latch lever sounds like a good idea.
