Then you don't have to unload everything when you get home, or load it up before you go there. I wouldn't be leaving my gear in a trailer where it can so easily get stolen, and only has to get a tiny leak and water can get in it, when you can load it into a car in 10 mins. Even if you lock it, 4 crundys could lift a trailer onto their own bigger trailer. Or just drill the locks out and steal all your shit Goodbye gear Yep I've herd of this happening... or one snip with a pair of bolt cutters and its gone... My trailer is water tight, and is locked to the car with re-enforced steel, when the trailer isn't on, it has a safety hitch on the trailer. it can't be locked to the car with reinforced steel.... just the tow hitch and a chain.... all that's holding the tow hitch closed should be a tiny padlock that you could break with bolt cutters... and the safety hitch is the same... bolt cutters to the 2 padlocks and its gone.... I'm really sorry dude but I'm a mechanic and live in a bad part of sydney where this stuff you learn at a young age... if your trailer was to be parked overnight on the street here... it would be gone. sorry dude
