I can always buy another piece of marine plywood.
Thoughts?

I would most definitely mock this up with something cheap like 1/4 plywood or even coroplast. With those beefy supports and hinges you shouldn't have much issue with support. Then you can use the old-fashion tuff test to see if you are getting separation.
With a 96 inch extension you
WILL need another set of lights on the end
(I'm doing something similar with my RV project - mocking things up and testing with wood before a start cutting expensive aluminum.)

I have no idea how that particular trailer does. I will say that many things that look aero aren't actually in real life. The wind tunnel tells the tale. (Even engineers that deal with aerodynamics for a living can be surprised after testing)
I am surprised that an almost $265K trailer has a cheap looking plywood interior like a budget van build. (Well after visiting an RV show I'm not that surprised - most commercial RVs are junk)
