I think I can answer this for you to some extent. We have the 19' CCD and it has the "dark" stained wood trim as you mentioned, and I have never really been crazy about it. Anytime you have a small space and put in dark elements, it makes that space seem even smaller. We love our unit though.
Our 19' CCD is the exact same floor plan, layout, etc, as the regular Bambi LS or Safari, or what ever they call it. The regular Bambi has the lighter "real" wood cabinets. I can't recall if they are supposed to be cherry or birch.
So, it seems that in this case, it would be as simple as saying to AS please install the cabinets with the lighter (nicer) birch? in my 19' CCD. The should fit in just perfectly. I wish that I had a least mentioned this when ordering, but then again, I'm not sure Airstream would do it. I know it can be done.
Your 16' is a little different, as there is know model "lateral" model of the 16' that they could swap out the cabinets. I would think it would then get into a customize thing, and that could run $$$$, and that's if AS would oblige.
Hope this helps.
Sometimes I wish I were living in the stone age. Then I would know I'm the smartest person in the world.
