I'm about to pull the trigger on some Wolfman Racks and Expedition Dry Bags. The portable washing machine feature was definitely the icing on the cake. I also read about one guy using the attached dry bags as portable coolers. He fills them with ice and about twenty cans of various high-end canned beer and thakes along a sleeping bag and tarp. He's got it all: Beer, sleeping equipment and fresh water from ice melting to wash away the morning hangover.
