Closing the problem
Not having a known Freightliner Shop, or Thor Dealer, within 3 hours I was hoping there were some ideas on where I could look.
Eventually found a brand new Freightliner shop within an hour and they found a couple of issues. Power Seat was a broken wire at the terminal connector for the fuse panel. The rest of the 12V issues were not getting power from the Battery. During the build process that bunch of wires was tie wrapped inside the battery compartment and tied off too tightly near the Battery. Over time they vibrated enough that they became loose and detached from the battery connecter. The connections were soldered and tie wrapped with a bit more slack.
The Rig heads back to the race track in 2 weeks...
