Congratulations and welcome.
If you haven't already make sure you download and read Ed's excellent crowd sourced Axis/Vegas owner's manual found here:

In addition make sure you log into the Thor Owner Resources page (have your VIN handy) and download all the manuals there:
https://www.thormotorcoach.com/owner-resource/
When you're done with that give Thor a call (also have your VIN handy) and ask for the construction/engineering drawings of the coach.
