For those of you to whom this has never happened, congrats but please don't assume it will not happen. I am sorry to break the bad news but it is early now, in about a month or three at the most, thieves will begin looting! I believe this is a good time to start preventive measures, an ounce of this is worth a pound of saved headache. Every single year we all read and share stories of mysery right here, our fellow Lco's have equipment stolen ranging from a silly $10 garden rake all the way to someone driving off with the entire loaded truck and trailer outfit. Yes, every single year! It is a really sick world out there, I think last year one of the guys had his entire load stolen twice! I'm not sure he's still around, but even one time is enough to put a seasoned business under, nevermind a new one. I've been pretty lucky but I had a backpack blower walk away, which, in 5+ years that's considered very lucky. Now I am not counting the few hundred dollars worth of numerous small tools and knicknacks that are just as easily missplaced, but you don't missplace a big dollar tool if you get my drift. Some of the measures I've taken and use religiously that help: 1) Instead of using the provided trailer tongue latch clip, I padlock the tongue's latch onto the receiver. > This also tends to prevent accidental miss-latching the hitch, at least for me. 2) Bought a locking receiver pin (that big pin that goes through the hitch itself). > They're not cheap, about $16... But why lock the tongue, if... > So they can't pull the whole receiver out of the hitch and hook that up to their truck's tow package, and drive off with your trailer. 3) ALWAYS grab the keys OUT of the ignition!!! > Lock the truck after visual confirmation that the keys are in your hand (so you don't lock them inside). > Buy a clip so you can latch it onto a belt clip as the keys hang in your pocket. 4) Use one padlock each side of the trailer gate, somehow make it so you can lock that gate when it's closed. > Yes, 3-4 guys can still lift your mower out, but it's not as easy. > At night, back the trailer and truck with the gate up against a tree! 5) A chain and padlock threaded through every handle of everything in the truck's bed keeps this stuff all in one place. > Yes, a bolt cutter takes care of this, but not every thief has this handy. > Do not assume your gas cans are safe. 6) Make sure your truck box and any tool boxes can be (and are) locked. Make no mistakes, the above will not stop the determined thief. But it slows them down, and it prevents the crime of opportunity. Hope this helps someone.
