Coroplast? Brake it at an angle to the corrugations to stiffen it.

I'm thinking of adding a "Belly Pan" to the trailer (Something light, like Formica) to keep the airflow from hitting the frame cross members. Also, surrounding the axle with an air foil (Red Oval)

Give the air foil a negative camber to keep the wheels on the ground at speed.
1/8" sheet ABS could be heat-formed, Formica not so much.

Yes. I just did a quick dirty job with Paint XP. I know the rear of the air foil needs to be tapered to a point, and the profile needs to be more like an airplane wing.
I like the idea of wheel pods.

Yeah, the Formica, or whatever, belly pan only needs to be flat. I thought of dropping it down in the middle to under the axle, but I think that extra frontal area would cause a higher CDA than just sealing the frame, and using an airfoil on the axle.
Do you think these additions are aerodynamically advantageous, or to much trouble for the return?

I'd not cover the axle, but radius the edges and cover the bottom half of the carrier up to the clamshell lip.
The wheel pants need to open up for access. Either Dzus fasteners, and a hinge at the top or pivot at the front to butterfly open.

Actually, I was thinking of filling the gap with a triangular box, with the apex just behind the coupler.

Edges of the frame not the axle.

Is this getting closer? Do you not think the 1.25" axle needs rounding pieces?
