Winnebago Adventurer Roof issues

With Comprehensive coverage, your insurance company pays for damage to your vehicle caused by an event other than a collision, such as fire, theft or vandalism. If you hit an animal, or if your auto is flooded or stolen, Comprehensive coverage will apply.

I somehow doubt if they will cover a design defect or a lack of owner maintenance which is what Winnebago will claim. I guess you will find out. I wish the OP luck.
