From our tour of the factory and some exploration of our unit....
The walls are framed with square thin-walled aluminum tubing. There is foam insulation between the tubing members with the interior and exterior skins laminated to the frame. Window/door openings are cut after lamination.
The floor is framed similarly, with ~3/4" OSB laminated to the tubing frame - no insulation between the members that I found.
