Which one ? Tiffin, Newmar, Prevost, Monaco?

Monaco side walls might not be glued, not sure what Ocean Mist was leading to, but in 2003 I was at an RPI camp ground in Unidilla Georgia and there was this beautiful Monaco Dynasty parked right next to my coach. We started a nice friendly conversation about his coach and I told him how nice it looked. He told me it looks nice from a distance, but look. He pointed to me some fine hair line cracks all over the side walls. He told me he was headed to Wildwood Florida to get the walls changed out because of the cracks on the Fiberglass. He told me that Monaco bought the fiberglass from Dupont and that they were getting the fiberglass walls removed at a big shop Monaco had just opened in Wildwood, Florida. That was also the time when Monaco had bought Safari and had major recalls on all their coaches. The thing is that I saw the exact same thing on a Country Coach that was for sale at the FMCA rally in Idio. It had the same hairline cracks all over the side walls. I did not ask if it was also the Dupont junk they were selling to a lot of these RV builders, but it was there. So I am not sure which is worse. Taking a chance on a side wall that is glued or getting a hung style side wall that has defective hairline cracks.
