The first thing you have to do is contact your personal insurance carrier or agent, and find out what your own car insurance does or does not cover with respect to rented vehicles -- and in particular, the particular type of van you will be renting. (Or you could just read your policy -- carefully.) Are you covered for third-party liability? For loss or damage to the vehicle?
