Gear. This is my 2010 list of things that at home and traveling are light weight and priceless. My sleeping bag from walmart, its black and grey, rated to 40 degrees and is lightweight synthetic. It rolls up, is big and incredibly warm.
I have both sleeping pads from walmart. one is long and thin and fits great next to the back rear seat for a quick sneeze at the end of the day. The other is short, wide and bumpy, better for home use but can be put on top of the other pad for more cushion, especially when the trifold bed isn't with me.
