Outer Limits 4x4 Board

I think alot of you are forgetting battery grinders and hand held oxys are pretty common now. Also something like that boat wont be stolen by a group of your average loganite thugs they would prefer the fishing gear or wake board that may be inside as its easier to hock. If someone is going to steal that they will know what they are doing and you wont stop or deter them.

you could always put 240 volts across the trailer tho im sure it would help to deter people

most aftermarket quality car alarms have additional 'triggered' contact switches that can be rum through a lighting circuit, eg driving lights, brake lights even atached to the earth/negative pin on a trailer socket.
once lights or trailer detached and circuit broken alarm sounds.
obviously this can be bypassed but there is no way to tell its alarmed.
serious domestic/comercial alarms have specific rersistor values for closed and open circuit so bypassing is extremely difficult.
jaycar used to make a simple addition for car alarms that could protect driving lights, can't see why this wouldn't work with a trailer.

i think Swerve is planning on towing his boat up to Logan from sydney, and is worried about it being pinched up here and not leaving it at home on the footpath. Am i right Swerve?

park it in (reverse it up against something)
put an alarm in it and when it gets set off, come out and give the prick a hiding

Apart from the obvious high quality hitch pin lock, try changing the coupling to one of the offroad couplings that not many people have (Orac? and so on) they may well be able to uncouple the trailer, but they will not likely have the correct coupling to tow it away.

A spot of welding around the back of the hitch coupling where it sits in the towbar assemby may give them the impression that the coupling has seized in the towbar even if they do get the pin out. The welding would easily grind off when the time comes to remove the hitch and would not seriously compromise the strength of the hitch.

Make it look like too much stuffing around is needed to uncouple the boat in any way and they will more than likely leave you alone.

Addit: for the vehicle a secret switch in the back of the vehicle going to the fuel pump. Nothing like getting a vehicle started only to have it die 100 metres down the road with a boat on the back. Cue the very rapid exit...

Where do you buy the GOOD chain, my local fastener shop, don't do chain, Bunnng is crap ?

Serafini Chain in Albion, Brisbane. REALLY GOOD CHAIN!!

Most lifting gear shop should have decent chain. Herc Alloy lifting chain is bloody hard to get through with bolt cutters. Anything thicker than about 10mm. Comes in nice yellow paint just to make it stand out.

I knock up this to discourage light fingered people.




However this is only to discourage... my trailer's not worth much...

My parents had a $20k Corrimal van pinched from the front of their house. They are trusting souls and had nothing to prevent this.... however my dad is very sneaky... they now have about 6 different things on their new van....
