For me, a start would be...
- A titanium frame for vastly increased strength and minimum weight
- Carbon fiber skin for strength
- Vacuum panel insulation
- High R value windows
- Kevlar or Spectra awning. Large disc brakes
- Lithium batteries and a roof jammed with solar panels...
I live in the REAL world, so I have been think about this very topic, on and off, for many months.
- An aluminum frame (2x4 or 2x6 x 0.187) 24" O.C.; same size tubing for cross bracing every 4'
- The roof has to be fiberglass or aluminum over PVC sheathing. I must have a 2" overhang on each so thath the jouint between the toof and the walls is UNDER this over hang
- PVC floor glued to 2" rigid foam, glued to the aluminum frame; additional cross bracing under the foam every 2'
- Fiberglass exterior walls directly over 2x2 aluminum frame with 2" rigid foam insulation
- Thermal pane windows
- Lithium batteries and a roof jammed with solar panels...
You might convince me to use marine grade plywood in place of the PVC, but only if it was real BS1088 hardwood plywood which probably costs more than the PVC.
