What is the best Ice Chest/companion way step out there? Anyone use a Yeti (Rotoscoped-molded) style chest? If so, what size? Researching for the best fit, and it looks like the Grizzly 40 would work well. Let me know what you all are using. If you are like me, the one that came with the boat has probably been crushed a dozen times by now. Thanks in advance.
