Ok, so this morning we went straight to Jayco. They took us into the Jayco factory and up on an observation deck above the 5er's to see the roofs being made. All the roofs inside the factory were smooth as a ribbon. Outside there was a row of 5er's that had just been either pulled out of the factory and some that had been there awhile. Some had no rippling and others had some, like ours. It seems that after they start to dry, some rippling may occur. We were shown and told about a new roofing material that is stiffer to deal with and a little harder to smooth out. It seems that while trying to pull it down into these spaces around the AC's, etc. it is more taut there than on other parts of the roof. Still wasn't 100% satisfied, though, as you wonder if people are blowing smoke.
We spoke with 2 different Jayco repair places near home and they essentially told us the same thing as Jayco. One woman even forwarded our pix to her Jayco rep and then called him. She was also assured it was normal and not a problem. She was very knowledgeable and they were actually in the middle of a complete roof overhaul right now. She was of the opinion that we would have no problems.
After talking to several RV repair and RV roofing people by phone, on forums and on RV fb pages, we are satisfied that things will be ok. This thing may turn out to be the biggest lemon out there, but we don't have a crystal ball, and no one can ever know for sure. We've decided to purchase it.
I have to say that Jayco was awesome today. I have called them probably a dozen times in the last 3 weeks. (Between the delivery proble, the dinette fiasco and this roof thing.) I'm on a first name basis with the switchboard operator and met her in person today. LOL Our dealer's Jayco rep actually left his office and work today and drove us to the plant himself to see the roofs made, took us through there and then to see the CS Manager. Really, how many factories will just take you inside, outside of a tour, and show you things up close to ease your mind? It really did give me a good feeling about Jayco.
So, thank you so much to everyone here for your help. It is so nice to have somewhere to go to get help.
