Taxa Mantis.  LIKE NEW.    It’s an amazing design and a great balance between indoor and outdoor.  
Should read a bit about the story. The founder of Taxa was the lead habitat architect for the astronauts at NASA.   So the design is really special and unique.  
Has solar panel, toilet, shower, full cooking, fridge/freezer, AC, heat.   Sleeping for Queen bed plus 2 bunks.
