2021 Bambi 22FB - Wall Framing Question

[Ed Wiz]

I’m hoping to make a larger dinette table for my 2021 Bambi 22FB. I’m planning to support one end on the original pedestal and the other by attachment to the exterior wall. I’ll be removing the cushion on the seat below the window and attaching the other end of the enlarged table to the side wall, below the window. I’d like to attach an aluminum angle to the sidewall and fasten that end of the new table top to that angle support.

I’d prefer to support this aluminum angle with screws into the sidewall framing of the AS. This as opposed to pop rivets into the thin, interior aluminum skin of the trailer. Does anyone have information as to where or how the sidewall might be framed? It is not clearly evident looking at the camper.

See attached photo.

Appreciate any help and/or suggestions.

Thanks, Ed

Airstream was nice enough to send me the Electrical Schmatics for the 22FB Bambi. This was apparently the most convenient way for them to show wall framing locations. This is helpful and confirms, generally that the framing follows the rivet locations, as expected.

Does anyone have any knowledge as to what this wall framing consists of? I'm assuming the framing supporting the exterior and interior skins is similar to metal studs or channels, but I have no confirmation of what or sizes, etc.

Anyone been inside these walls?

Thanks, Ed

As a follow up, I obtained details from AS regarding interior wall framing. This is for the horizontal member directly below the dinette window on a 2021 Bambi 22FB. Details shows a Z shaped member. Outside adhered to sking with double sided tape, interior skin via rivets (2 I recall). Hope this is helpful to others. See attachment.
