Isata 3 Interior Wall Bubbling Behind Toilet
We have a series of "pointed" bubbles extending down from near the ceiling to a half way point behind the toilet in our Isata 3. I stopped by the dealer on the way home last week and they claim it is moisture. That is an obvious first guess, but there are no obvious points on the roof or awning attachment that would contribute. I am taking the motor home in later in the week for a closer inspection. I know there is foam behind the wallboard and initially thought maybe there was a glue issue or staples protruding. But the pattern on bubbles doesn't support that and it has gotten worse. The vent fan is always on when we shower and moisture doesn't collect on walls. I will attach a photo in hopes someone has had similar experience. (The photo is rotated 90 degrees.) Any ideas of the cause? My second concern of course will be the repair. The dealer is talking of a potential overlay of a new wallboard. I have a better approach, but will wait to see what comes out of the inspection and whether or not this might be a warranty issue. Based upon prior experience, I am not too confident in the dealer's service facility.
