Here's our camp from last year (edit: our virgin year), just after the rain and the double rainbow. My girlfriend and I had a 12-15' conduit dome and built our shade structure using only a canvas tarp, three 2x4's, about 150' of rope, and about a dozen pieces of candy-caned rebar. We wanted to be comfortable and completely self-sufficient, but our requirement was that everything had to fit in my Impreza wagon without completely destroying the suspension on the 1000 mi drive.
We adapted our shade structure from Camp Elsewhere's designs. http://www.bweebweebwee.com/tensegrity/

And our bedroom, nice and shaded so we could sleep past 8am.
Finally, inside our dome, which was our lounge, storage, dressing room, shower, love nest, and general home to shenanigans (except during peak hot hours -- we learned that it could benefit from better ventilation):
