I've heard that it's usually cheaper to insure a camper than than to insure the same van in its original state. In quotes I've seen this hasnt been the case, but it might be becasue I'm a relatively new driver. Can I insure my van through the usual means, or do i have to tell the company if its a camper? is there a grey area? when does a mattress in the back become a 'camper van' is it a certain amount of amenities?
