Hard Lightning

Good evening all, This is our first post, we are in the process of purchasing a Vellfire 2.4L day camper and as part of the insurance quotation the brokers have requested the vehicle has a tracker and immobiliser fitted …is this a common request as it has been implied that this is a requirement from most insurers? Any insight would be appreciated as the pool of insures appears limited for Japanese imports of this type converted to a camper. Any feedback gratefully received.
