I have just been told that I have a tracker on my motorhome and I am trying to decide whether to activate it or not. What are others experience of these and specifically has anybody been unfortunate enough to have to use it? If so did it work? Were the police good at looking for it, as I wonder whether it is at the top of their priority list? The one I have installed is a standard monitor, but Tracker are also offering me a replacement GPS unit that will allow me to track it myself. More expensive, but is it worth it I wonder?
