RE: [Hammock Camping] sleeping in the PeaPod...
One thing I do is loop the cinch cords around my tree rope
and tie them off with a tautline hitch. In effect, the
peapod is slung the same way as my hammock, but with a
little less tension.
I found that no matter how much I tightened the cinch cords
around the hammock end, the peapod always slipped inwards,
and drooped as you described. (Mind you, I don't have a big
hammock knot like there is on a Speer hammock, as I'm using
a tropical hammock.)
