Without seeing at least pictures, it would be hard to say. I can't picture any body seams like you describe. You say it is "all under the clearcot" but that you "can reach up behind it" ...do you perhaps mean you can get your hand on the back side of the body panel? I cannot picture anything that sounds "normal" about the way you describe it. If you have any questions at all about it, I recommend you have a dealer service dept take a look at it, and don't stop prodding until you have an answer you are quite satisfied with. Another good idea would be to communicate with Winnebago Owner Relations at [email protected]
. You could send them a digital picture too. The email communication would document your problem in writing, and the date of the communication, in case you need that reference later.
