I have had 2 caravans stolen, they wont get the third we have 2 anti ram posts fitted and a phantom proactive tracker fitted, and it does work the dealer set it off whilst it was being serviced !!
Please be careful we had a caravan stolen, which was recovered ad later written off by the insurance co whom sold it on, the chasis was twisted, i would hate to think that it was sold on, but who knows !!!
We got a really good doscount from Tourer Select for having a tracker fitted, brought our premium down from 750 to 400, a tracker is well worth it we have had 2 vans stolen, and we have also istalled anti ram posts on our driveway.
we are still awaiting inspection of the caravan which has been towed from essex to wolverhampton for free storage by the insurers, we await the outcome
