You might want to double check that, generally the aluminum floor joists run parallel with the main frame and since they are on 16 inch centers, there is one joist at the wall and the next one is inside the frame. That does mean that directly above the frame, there is no floor joist, just the Darco type underbelly fabric, insulation and then the plywood subfloor. I think that is what you are observing.
If the sub floor stopped at the frame, then the top of the outriggers would need to be about 2 inches higher than the top of the frame, otherwise the floor would not be flat the entire width.
In truth, the floor is not attached directly to the frame and makes almost no contact with the frame. Instead the floor is only bolted to the outriggers and then the walls attach to the floor with straps around the perimeter. These attachment points are hidden by the exterior lower skirting panels. There is a second fabric layer attached to the bottom of the frame, but it just encloses the tanks and other items and has absolutely nothing to do with the sub floor.
