Thanks for the welcome!
Don't know about the step recall yet. I learned of it after I got home, but will find out.
Already got a call from Thor customer support (which was a nice touch) so I know my purchase has been registered with them. I have the build sheet but will have to request the other items you list. Again, thanks and I look forward to the many resources this forum supplies, especially experienced owners such as yourself.
