Some extended warranty insurance is a scam. Some very good. We were lucky to buy the extended warranty on my wifes car, it paid for replacement of the air suspension and several repairs after the manufactures warranty expired. Paid for itself several times over. I would re-read your insurance policies closely and if it infers you should have been covered or the salesman represented to you that you would be covered I would go to the consumer protection division of the Attorney Generals Office of your state. I would also file a complaint with the state Insurane Division. Some times a call from either will cause the company to re-think its postion. Good luck PS Just re-read your post, you may want to call the Winnabago Factory as you said it was still under warranty. I would make them pay period, you may want to consult an atterny as someone placed your life in grave danger. I once paid my attorney $2,000 to save a $75.00 overcharge for and eye examintion. We won and I would do it again before I would pay for something I do not owe. My attorney got a kick out of it and refused to keep my $2,000 in the end after he earned it.
