I'd love to know how heavy and how aerodynamic a bike trailer can be and at what speed it can still be moved at certain points.
I was thinking about a bit wider trailer (~1.2m) and rather long (4-5m) but the top is like a hat or deep lid that can move down for transport or taken off. So you have less aerodynamics when moving. And enough width for a nice comfy bed that turns into a recylinging armchair with a topper. And solar.
But I'd want to pull it with a tadpole possibly with a 250W motor and still reach ~15kmh. This is all just fancy ideas so far though.
I'd bet with materials lighter/stronger than woodyou could do a bit bigger, especially with an eye towards the effects of wind. Possibly with a separate motor/brake situation?
The camper might need an extra brake yeah. But you can only have 250w motor here. I was thinking really lightweight XPS with carbon. But the stuff you put in is probably going to be 200kg at least if you want to "live" in it like with vanlife.
There is this "lightship RV" trailer (video) for electric cars that uses this concept of a somewhat round / elliptical shape and lowering top half. But it would need to be lighter and thinner.
