Graybeard,
They are insured just like a car, fire, theft & oops I screwed up. I think it's a $100.00 deductable.
Auto Owners will let you add atv's & snowmobiles to their policies. But they won't give you much slack if you keep making claims. My feeling is they are doing you a favor, don't abuse it.
A friend had his snowmobile on his homeowners policy, the 2nd time he wrecked it........bye, bye...... cancelled.
