Now we know...

The 12 mile round trip to the scales went well.  The scales showed the TH weighted 7600-7700 lbs including the trailer itself.  My Tundra did a great job pulling the load. After returning, Mac successfully backed the Tiny House into the side yard.  The only issue was the door didn't close/open easily.  After leveling the TH several days later, the door returned to normal operation...as is typical of RVs. I have no worries that I can finish the house with 2000 lbs, keeping the total gross weight under 10,000 lbs.
