I was concerned about not having places to hang during my bike ride across Missouri. Therefore, my nephew and I used tarps that could convert to a tarptent for two.
I used polyurethane coated nylon for the tarps--a heavy material, but pretty tough. I did a hex-shape for my tarp, and DIY Gear Supply's Winter Dream design for my nephew's. The idea was that if we couldn't find trees, we could string his tarp between the bikes, and use mine for a ground cloth.
It would be nice to have a more integrated solution for a single camper.
