a lot of vague details in regards to the insurance coverage. In general theft would normally fall under Comprehensive as mentioned previously. If you do have insurance coverage for the loss, then insurance company is going to pay whichever is cost effective between either repairing the vehicle, or totaling the truck. Being a complete rollover and the severity of body damage, in this case it's going to be a total loss and insurance should pay for the actual cash value of the truck. This is not retail but rather what your truck is worth. If you run an average nada quote that should get you in the ball park of where insurance should be for a baseline, then +/- based on condition, mileage, accessories, etc. Any reputable insurance company should be paying a reasonable amount for your truck. They aren't out to give you a profit on the vehicle, but they should fairly compensate you. Make sure they provide a written breakdown of how they arrived at their figures. This is your insurance company, you pay them money to insure your belongings so they should walk you through the process.
