IWS Storage Box Setup (Ski Box and Skinny Box) – Our personal favorite combination for storage at the back of the Baja. We love having the tall Ski box, which is obviously made for skis, but we also use it for fishing poles, rifles, paddles, or recovery shovels. On the other side of the trail, we put the skinny storage box to just give you even more storage. These boxes sit on opposing sides of the spare tire. ($4,800 in options)
