Frank: Did he actually locate the source of the leak already? Or are they proposing to change a lot of things before the leak tests? Just wondering what PC response will be to a company that is trying to hit the problem with a sledge hammer when it might be a very small issue. Hopefully they took some pictures to back up their claims that things were done poorly. Otherwise I'm not sure PC will take them seriously.
Either way, I really hope they come up with a speedy, effective and permanent solution for you.
When I picked up my 2552 I crawled around on the roof and found a couple of areas around the shower skylight that looked like they might become problematic. The tech Bobby at the factory went right up and repaired the two bubbles I found. So far have not found any leaks, fingers crossed. (for both of us)
