Trailer Coupler Lock

People have had their RVs stolen from their driveways by creeps who carry bolt cutters. Some people try to make their trailers less appealing to thieves by adding heavy duty hitch locks. Many styles are easily overcome by a thief if given the right opportunity. My sister-in-law moved her pop up camper to her front yard and put a for sale sign on it. The next morning it was missing from her yard. It had a good padlock on the hitch.  She did not get nearly what it was worth from her insurance company.
