"It could still be taken apart but it will surely slow someone down."There have been a couple trailer thefts in my area lately. It seems like the thieves have a new strategy for stealing a trailer with a lock on the hitch. My trailer has been sitting in my yard with a Master trailer lock which has a ball on it which fits into the coupler and locks in place. I also run a bicycle padlock through the safety cables and the hole in the coupler's unlocking handle.
What these thieves are doing is to remove the entire coupler from the trailer and replacing it with one of these: Ball Coupler - Harbor Freight Tools
Remove two bolts, let the original coupler hang and install a replacement coupler and tow the trailer away.
Now I have gone a couple steps further and I have put a weld on the bolts and nuts which hold the coupler to the trailer's framework. It could still be taken apart but it will surely slow someone down.
I also bought 2 cable combination bicycle locks which will go through my trailer's aluminum wheels and tie the wheels together.
All of this is an inconvenience when I want to move the trailer to mow grass under it but replacing a $15,000 Blizzard enclosed trailer with four sleds stored in it would be a much greater inconvenience.
Lord, I hate a thief!
That part right there is the most important part.
If they want your trailer they will get your trailer. Anything you can do to slow them down might make them pick a different trailer or someone might notice before they can get away. My trailer is at my business in a gated lot with a camera system yet I still have ball coupler lock, pin lock, and cables around my tires. Also there is absolutely no indication of what is inside my trailer other than it has front/back ramp doors. The way I see it is that a huge Doo sticker on the side of the trailer makes the trailer more of a target. People suck. Even if you lock it up and take extra precautions they still will try and steal it.
