I would go on the roof and take off the cover for the fridge vent up there. (Scrape out the goop on each of four screw tops to unscrew) Look down with flash light for any sign of water above the lower side vent. Around the vent is the Dicor that might be flawed--easy fix. The wind might have forced water up and over under the cover, but not likely.
Side compartments, look up inside for any wire access holes not sealed so that water might be from the wet floor too.
How can the side vent be buckled and still fit? Also it is plastic. is the opening out of shape too?
Horror story-- a tree fell on a friend's Class A in the middle, and squashed/twisted things some up and down its length, not just where the tree was. Eg, the front window won't fit back in. Not very likely, but if your rig was "rolled" and repaired to be sold as new, things could be out of shape and could have leaks. (Very unlikely)
