Extra security

Is this for when you park at home/in storage rather than on site? I’d not recommend one for site use both from the point of view of it being a right pain every time you want to move the van and for the weight which will need to be carted around reducing your payload.

You'll find some info regarding wheel clamps for caravans (not many people use them on MHs) in the following link-

Have you considered a steering wheel lock which is also a visual deterrent? It can easily be carried in the van when out and about and can be used home or away without hassle.

Any security is better than none, but seems to me that most of those mechanical security devices can be overcome by a determined thief with an angle grinder or crow bar often leaving much damage in their wake. Alarms are just an annoyance going off for no reason in the middle of the night and most folks ignore them. Factory immobilisers are easily overcome with gizmos plugged into the diagnostic port. 

I’ve fitted a tracker with a series of sensors that will trigger alarms (SMS message to my mobile) for excessive vibration, battery disconnection or vehicle moved. It also includes the option to trigger a relay connected to whatever you want to immobilise the vehicle e.g. fuel pump. They’re tiny and can easily be hidden in the dash board. At least if it’s taken, they won’t need to do too much damage to take it and I’ve got a fighting chance of recovering it. Mine cost around  £60, similar amount for gps service each year and about £12 for 50 SMS messages.

I had an unfortunate experience with a Milenco wheel lock on a previous caravan when it jammed! Must have been good as it wasn't easy to get off. I had the jack the van up and deflate the tyre inorder to get a spanner to the wheel nuts. Once the whole thing was removed it was easy enough to disengage. 

With our motorhomes we have gone down the route of having a Strikeback alarms fitted by VanBitz. Not cheap but highly regarded.

I have one of these for at home, wheel trims have to be removed to fit it properly though.

And now I have one of these for carry on security which is easy and quick to fit without having to remove the wheel trims and fits to any of my wheels to compliment the steering wheel strong arm I always use

I have the auto-watch Ghost Immobilizer fitted to my camper van, (£399 fitted).

Before you can start the engine you have to put a special code in by using the buttons on your steering wheel or you can link your phone via an app to the immobilizer to start the engine.

No gizmo by a thief would be able to get round this.

I watched a program a few weeks ago about car thieves and they can  steal a vehicle with a tracker they can block the tracker signal and then use a device to locate the tracker(s).

I expect Southdowns Motorhomes wish they had fitted an alarm. They had a Burstner Lyseo TD 736 Harmony Line stolen overnight.

I keep my MH in a barn about a mile from my house.  To save having to check it every day or two, I have recently installed a Vodafone Curve GPS tracker in my motorhome.  I use the associated app on my smartphone to monitor its location and use the "saved zones" feature which sends my phone an alert if the MH moves outside a user-defined perimeter.

This set up works very well for me as my storage has an EHU so although the tracker has its own battery which lasts about 5 days, I can plug it into my mains supply to keep it fully charged.  Alternatively if EHU isn't available, the tracker can be recharged via a USB lead off the solar powered 12v system.

The Curve cost me £20 to buy, but there is currently a Black Friday deal for £12.  It costs £2 a month to run, added to a Vodafone mobile account.

I had a well protected motor caravan sized vehicle stolen a few years ago.   It was simply winched onto a recovery vehicle . . !

Have you had a dry run by moving it outside it’s expected zone to test it works Jim?
