Hi,
Obviously late to this thread...have a 2018 Tuscany with almost all of the same issues. Shower not draining(no valve under sink), mounding fell off (the large one across the slide) and mirrors not mounted per manufacturers specs (yes I called them and they said they have received a ton of complaints from Thor owners) as well as Aqua Hot issues (same comment from Aqua Hot about Thor) lead me to believe Thor must know about the issues during assembly but choose not to do anything. I am at my whits end trying to talk to them. Bottom line is in fact is bad manufacturing and sales to an unsuspecting public.
Sorry to vent, this rig had 7000 miles when I bought it and it has been falling apart since I did. Shame they are buying everyone up, there will not be anything built with quality that you can purchase in the future .
