I added a bedroom to the trailer, since it was way too tiny in its original configuration...
One wall has been removed, and its place I have a roof panel that swings up. you can see some of the other panels for the walls/floor of the bedroom still packed in the trailer.
add corner support (angle iron)
both walls and the floor have been bolted on
exterior after setup. the unpainted part is where the air conditioner goes in
grey water tank is under the trailer, the blue tank is fresh water. I've found the lowest cost and best results for solar heating the water: put a clear plastic bag
around the blue jug, and let it sit out in the sun all day and by early afternoon it will be 25F warmer than the ambient temperature (75 ambient 100F water).
here you can see the water jug heating up! Someday there will be a window on the side wall, for now it's filled with foil-backed polyisocyanurate insulation.
inside: the bed with skylight to see the stars
sink... I found that a marble floor tile makes for a cheap heatproof surface for cooking.
grey water tanks sitting on the shower pan. plumbing for the sink in upper right
shower is attached to ceiling with velcro.
