Possible frame weld broken on new Montana

Spent a good part of the morning at the dealer. The new GM was not in today, but the retiring one was, so he and the service manager called Keystone separately. Before I got home, about a 30 minute drive, the service manager called and asked me to call the Owner Relations Dept at Montana. So I did. The woman I spoke to had no idea why I was calling at first and then began to slowly figure it out. Unfortunately, she had not been briefed on the problems at hand. She said she wanted to ask me some questions about the possible frame issue. I stopped her right there and said, "If that is the bank of about 20 questions, Iv'e already answered them TWICE before and see no need in answering them again." There was silence. She then stated that since it was a new claim that it had to be started from scratch. I nearly lost it. I started a few words a little more angry than I should have. I then apologized to her as I think I came across a little strong. I told here this was not a new claim and that it was an ongoing problem that had been attempted repairs done 3 times already. I then told her my VIN# and told her to look up the case file and the email that was sent to them by me last week. She took about 15 minutes or so and came back on the line and apologized. I then told her that I was not angry with her, but that I'm tired of people there not acknowledging the problem. She asked If there was anything new to the case. I explained that I was very concerned that every time the caulking seal was broken, that water would get in and eventually delam the left front of the camper and then I would be upset. She and I talked for another 20 minutes or so and she asked to put me on hold again. When she returned, she asked if I had thought of anything else I'd like to say as this case is being forwarded to upper management. I told her that I would like for them to review the shoddy welds within the wall of the camper, along with the videos that I've sent them links to, and then tell me if they are happy with what is seen. I told her that I was extremely unhappy at the quality of work uncovered and that I was actually mad at myself for thinking that Montana may have a better product. She told me that someone would be in touch with me soon. I kind of laughed at that because the last time anyone contacted me from Keystone, besides an answer to an email last week, was back in late July. And that was to be told to be looking for an email for instructions!
I'm not hopeful to be honest here guys. I'm only hurting myself thinking about this continuously. I've been as patient as I can be, and for those who know me, that's been pretty hard. So, I guess the ball is in their court once again and I'm in a holding pattern.
