We had hail several times during our travels and never had any damage to our coach. All it takes is a walk around and an inspection of the roof to determine if anything was hurt. On older coaches, with brittle plastic covers over the vents and AC, there is a possibility of them being damaged but for the age of your coach, I doubt if you have anything to worry about.
On a side note, if you are looking for a toad, and don't mind a few small dents, right after a hail storm is a good time. We bought an almost new Chevy from Enterprise Rental that had less than 10,000 miles. It came with the full remaining factory warranty and from 20 feet away you could not see any damage. We paid about 1/4 of the MSRP for this vehicle and it served us well now for several years. I have painted several vehicles and fixing small hail dents is not that big of a deal, if it really bothers you. In any case, since most car rental companies "self insure" they just dump any vehicle that has hail damage.
It did come with a clean title and Carfax.
