i've had s***stolen before, but not that much....damn. Sorry to hear. I think insurance covers anything bolted on or anything you have receipts for, i think you have to claim the stuff and make your insurance premium go up to begin with, but it'd be worth it for next time. just fyi.
With my luck, I'd get that SHOCKING alarm and open the door without turning it off and juice myself....haha. I do that all the time and set my alarm off....oops, my bad.
