1) - Larger than a normal teardrop - we are both tall people and need elbow room.
2) - As light as practical, because if all goes well we will be towing this trailer behind an electric car.
3) - No need for a built-in galley. We were both amazed that the #1 reason people seemed to want galleys is because they need coffee in the am. Well, we don't drink coffee, and I figure a campstove, cooler and possibly microwave will suffice.
I finally whipped up a plan that looks like this (apologies for the chicken scratch - I tried SketchUp and couldn't make head or tails of it.)
Another parameter is that it has to fit into my garage, which has a 6' 4" HVAC trunk that it has to fit under.
I laid out cardboard in my garage and we decided on a plan with two transverse beds on either end of the camper. I'm trying to keep the foamwork as simple as possible, but am already dreaming of a nosecone on the front to get more aero.
Lightness demanded an aluminum frame. I had a very hard time getting anyone to build me a frame - all wanted at least three to five months lead time. Finally found a guy that built me a 6'6" wide by 10' long frame. To keep the camper as close to the ground as possible, I bought stub axles:

...and adjusted them so that the bottom of the trailer is only 9" off the road:
I've started making the floor, practicing my new skill of routing slots so the pieces can overlap:
Glued two pieces together, went waaaay too big on the Gorilla Glue:
After a day of work, it's starting to look like something:
And the dog likes it so far as well.
More pix soon - I'm trying to make this build move so I can actually try it out before the end of summer.
