I took my first overnight camp trip and all of my equipment worked out well except for my sleeping bag. Fortunately, I live in Arizona and I didn't suffer too much. I'm using a single-wheel trailer w/o panniers and so I'm trying to keep bulk down.
My problem with my bag was that it wasn't big enough to zip around my chest (it is a mummy bag) and I'm having a hard time finding one that will do the job and not take up all of my trailer room.
Additionally, what do you like for a sleeping pad that isn't too bulky but allows for insulation and enough padding that you can get some rest. I don't want to spend another night like the one I just had.
