Thanks for sharing. The trailer looks functional, but I admit I'm put off by the cobbled together appearance, sort of a "Beyond Thunderdome" aesthetic.
The suspension looks like a simplified version of the "twin I-Beam" independent front suspension used on Ford's 4x2 light pickup trucks for 30 years. I wonder why they didn't use an independent trailing arm suspension.
I'm uncertain about the materials used to construct the trailer. The frame looks like it's aluminum stock. The white front part of the trailer body looks like some sort of composite, while the dark rear section seems to be aluminum sheet.
