Nice job, well thought out. I have a Shappell Bay Runner. Love the shack but with all the gear in the shack it's a hard to pull for a long distance. When I can drive on the ice with my truck it's a great shack. I can hole hop without folding the shack down. But I need something for early ice and late season that I can pull by hand without feeling I might have a heart attack. I plan on cutting back the gear I take along when I have to walk. I do have electric drill with an 6 inch auger, so that's pretty light. Your design has got me thinking, but I want to built it super light. Thanks for sharing your ideas! Beeler
