Vehicle security for long road trip

i don't know about your policy, but mine explicitly states that theft is covered in the event the vehicle is not recovered.

items in the car are not covered (say, tools, a phone or a dagger) but depending on your other insurance policies the junk in the trunk might be.
So I googled it and you are correct but there are different levels of comprehensive so to be technically correct, the comprehensive insurance that covers theft or damage due to theft is called "fully" conprehensive insurance. Learn something new every day. Thanks for rousing my curiosity.
