Well it's quite simple: the trailer need to be as small as possible. The horizontal dimensions are set by the bed base, which I wanted to be full size, and the vertical dimension is determined by my ability to sit fully erect inside, which is something I want.
If I had made the usual teardrop shape, with the round shape at the front and the receding profile at the back, the door would have had to be at the front, which means my head would be at the back where the profile is lowest. Or I'd have had to lengthen the trailer quite a bit to use the low profile space at the rear as a separate kitchen space or for storage, and leave the front space high enough to sit in.
But the trailer is already ginormous: the velomobile and the trailer behind are 18 ft in length, which I reckon is already barely reasonable for a human-powered vehicle. It really doesn't need an extra 3 feet just for the sake of a slightly more aerodynamic shape. What's more, given the weight of the thing, I'm not sure aerodynamics is a very important problem
