Dealer refusing to do Warranty work?

Update - So far today I have talked to Winnebago and the servicing dealer. Winnebago has reviewed my list of repair items with the dealer and authorized all listed items that could reasonable be construed as covered by manufacturer warranty. Some of the items I had listed were considered invalid (for instance, when I set my stereo to the "b" speakers, there is no sound.. that is because there are no "B" speakers in my RV... ok, I can accept that :)) At any rate, the dealer has now agreed to proceed on all the items that Winnebago has authorized. I consider that completely acceptable. A few other items remain, but in all fairness, I completely understand why they should be addressed by the selling dealer. All we got to do now is wait and see if everyone delivers on their commitments. Just like the comments heard from the optimist as he was falling down the side of the Empire State Building... "So far, So good!"
