I have 2 Big Backpacks for sale, or would trade one for a good working 12 volt battery charger. I am asking for $25.00 each. Both have 6 zippered pocket compartments, all the zippers work good, plus the big compartment on top, map pocket, padded shoulder straps, waist belt, and sleeping bag straps. The orange one is a Large Cruiser by Camp Trails, it has some peeling of what I believe was a waterproofing on the inside, but it doesn't effect the usefulness. The red white and blue one is an All American sold by K-Mart, send me a pm here on moab or e-mail steve at Seney621@att.net thanks for looking.
