Cool. Coroplast is not fit for purpose. It's fine for mockups and experimentation, but the final material should be Polymetal or equivalent (Alumapanel, Grimco Maxmetal).

It cost more than plywood but is 1/10th the weight. The samples shown were sheared, rolled and braked by hand.

It is pre-finished and would match the build quality of your trailer.

The frame design was from the RV thread... I was thinking of just doing the 4 corners, and picture-fame (tying 4 sides together at center).
Polymetal has sufficient shear strength, you could make it a monocoque box. With Cardboard Aided Design or Coroplast, you'd want a frame that is triangulated.
