If I leave the trailer for any length of time or the area is sketchy, I chain two wheels together with bolts. I have a metal strap with hasp and padlock that I am going to be installing on the entry door. The strap will be through-bolted into the door frame and reinforced on the bolt mounting locations, inside. For a thief to enter, he will need to cut either the lock, the hasp, or the heads off the bolts. Not many are going to go through all this to steal my trailer. There are many newer rigs that are better targets. Locks and chains are to keep semi-honest people, honest.
