Damage to fiver due to road construction

Not with an RV, but many years ago, I lived in a small mobile home while in college. the road I lived just off was being widened and they were blasting away at the hill to make the grade less. Somehow they messed up and rock blew all over the neighborhood. Several of us had rocks come crashing through our roof.. I was in shower, when trailer rocked and then loud bang.. as I hurried to dress and find out what was going on found a fist size piece of granite on floor of closet. It had come through roof, clothes in the closet and still had enough force to tear the vinyl floor. Company was very quick to temporarily cover the hole and get a repair guy to fix my roof... think the pictures in the newspaper and the thought that they could be fined for their bad blasting made them be quite eager to fix any issues we had. Not sure about the drop in highway, but good luck in getting the company to cover your repairs... Make lots of pictures, contact your insurance company and let them fight the battle for you.
