If the Airstream design, past and present were truly " monocoque" they would require no frame at all except for stubs to attach axles and the tongue.
I imagine the designers were trying to draw upon the concept but the structure at the floor attachment was insufficient over time and heavy use. In essence the body added little rigidity to the frame.

It's semi-monocoque.

And then they wonder why the seams leak when the whole shell is flexing.

Yep, IMO if these trailers had full length floor joists, twice as many of them, and a perimeter structure where the outriggers now end, double the wall joists, it would have been much stronger even without a frame.

Just look at an Avion frame.

By skid plates do you mean the extra bit of frame at the back below the main frame rail? Removing that will weaken the frame.

Our AS will stay in storage.

That's correct Perry. I call them skid plates because that's how they were referenced at the dealership. They don't actually a plate
