I have 2 of these. I have 2 followers. I've had 2 trailers stolen in the past. I haven't stolen a whole trailer since I added the synopsis. I had broken into a closed trailer, BUT the whole trailer remained because of this trunk. Anyone who wants to upgrade it will find another, simpler one. It's light yellow, so it's noticeable that it's there. I think the weakest link is the key lock, which is a small piece of metal that can be bent. If someone had a crowbar and that ordinary triangular handle, they could get it. I put in a few different locks and made them "hard" so others were easy targets.
