Welcome to the group. Go to this link on the Thor Motorcoach website:
https://www.thormotorcoach.com/owners
Establish an account on that website and register your motor coach (VIN, etc). Check out the resources and you should be able to download a plethora of information on your specific VIN to include all the components in your build, schematics, build construction drawings, owners manuals for all the various components.
Secondly, if you have any questions about how something works, concerns, questions about problems -- post your questions here. You'll find tons of other owners who will help you rectify problems, provide hints, and make suggestions about your concerns. Lots of friendly, helpful owners here.
Enjoy your rig. Happy trails!!
