The comfort thing is true, but I carry a 10x12" tarp and enough line to rig it up to some trees. It can serve as a cooking shelter, or a way to keep the bike from staying out in the rain all night.

Really I'm looking for something just to sleep and change my clothes in. The clothes changing may be more of a challenge with the hammock. On my first/previous tour that's all I really did in the tent anyway so the extra room seemed gratuitous.
