My dealer told me that orders were taking longer than normal, because they slowed down production to address quality problems. I also just read on a Thor Motor Coach Owner's Club Facebook page (was posted three weeks ago) a claim that coming from multiple reliable sources, the same thing my dealer said.
So, obviously doesn't help people with problematic coaches, but hopefully it means that there are more coaches being produced in the future (and selfishly hoping my coach) that have fewer problems. There are many very happy Thor owners, some with few to no problems, others that have enjoyed it after dealing with manufacturing issues.
