Homer,
You know, this situation happens more times then I care to hear about. It sounds like your like your no different then rest of us. There are things in our coaches that we just haven't used since we took delivery of them. For one reason or another we just haven't used them, then when the day comes, maybe like in your case and in mine, we decide to use the phone system and find that a jack or two don't work. Winnebago's reply to this "your coach is out of warranty". Yea, like warranty had any thing to do with it! Quality Control missed this and Quality Control should be responsible for it, and the Predelivery Inspection by the Dealer should have caught it.
If Quality Control performed a test of all systems before the vehicle left the factory and the Dealers backed those tests with their own tests, which is what we have paid for, I would imagine that 98% of the call backs and warranty claims would be eliminated. There will alawys be those instances when an item will fail for one reason or another, if that happens, we can only hope that it happens within the first 12 months.
