I'd like to do something like this....6' wide deck with two 3' folding railings that lay flat over a steel/redwood deck. The two sides can fold up for a railing or lay flat for a deck extension/footrest and then a hammock or skychair could now dangle underneath it along side the bus. I'm a sailor and love rigging so whatever uprights i extend from the deck would likely have pulleys and lines or even a winch to raise and lower the sides if its too heavy, then rig up a shade sail atleast and then i can use my portable hammock stand if thats simpler... Then glue astroturf to the rest of the roof...I really like that idea that Jax did...even around/under the solar panels so you can lay down to work on stuff, etc...
