Bruce -- did you use the contact form on the Thor Motorcoach website under Owners Contact Customer Care for your email? Here is the link:
https://thormotorcoach.com/motorhome-owners-resources/.
The reason I ask is because I have used that link and contact form about 5 times requesting drawings and at least 4 other times asking questions and I normally get a response back from Thor within a few days each time.
