One side of the hammock can attach to any point on the bus. And use a spiked pole for the other side..
Or make 2 arms that attach to the bus and hang it alongside the bus, almost like an awning set up.
Just off the top of my head.
Home Depot sells fence post spikes that go on the bottom of a 4x4 post... That could be the side that goes in the ground.
