I didn't have a tracking device on the van mostly due to the initial and ongoing cost and I know what some will say at what cost a stolen van but have just bought a GPS Tracker for Fourty Five pounds measures 5 cm x 5cmx 2cm connect to live and negative send it a txt and it sends you a location it has a top up sim installed and as long as you send txt within three months it's always active so if van disappears you hopefully stand bit of a chance
