I want to create an ultralight teardrop that my EV can pull without seriously limiting its range. I have an old boat trailer (4' wide between wheels/fenders) and I was going to convert that but maybe I'll use its axle and go this route instead. Anxious to hear from the engineer types to see the precautions of a chassis like this.

This trailer design is not new - there's some OLD posts around here with the simple A style chassis.

Think unibody versus body on frame. Or airplane versus house.
Very exciting.

Qbill, are you referring to a floor built with a proper torsion box design? For instance with ply and laminated ply sticks of ripped ply like Glulam? That seems like it would be an easy, DIY structure. A bit more labor involved in the construction but very strong and durable.
I'm thinking DIY glulam of appropriate dimensions, maybe 1 1/2" square, sandwiched between 3/8 plywood and properly sealed from road splash. Does that make sense?

I've been admiring the Pico chassis since I started my first teardrop in 2016. I even researched doing the A-frame out of lumber which doesn't seem like a great idea.

Whether the skins - and I presume plywood for teardrops is most practical - are separated by rigid members, honeycomb, foam, or other - is secondary. SIPs are just another variation.
