While having concrete poured for parking RV at the house, I need to put it in storage. Placed is gated and all but what do y'all use for king pin locks? I don't want to spend a fortune on it...
In a situation like that, you are trying to make your trailer require more effort to steal than the one next to it. Thieves are usually lazy and will got the path of least resistance.
If they want your unit specifically, you want it to take as much time as possible. Time = an increase in chances of being seen. If they feel the tradeoff is worth it, then they may eventually win. If they have enough time and really want it, they will eventually win.
