I have a 2015 Autosleeper Nuevo which has a factory fitted immobiliser. As a solo traveller I would like to have an alarm fitted, my dilemma is which one? A Thatcham category 1 is a pre-requisite based on enquiries with different Moho insurers. the Strikeback by Vanbitz is currently topping the short list but it is expensive! I’m based in Hampshire.would be glad to have your thoughts and advice. TIA
