Eskimo Quickflip 3
Also, here's a ton of info/ideas on making a "smitty" sled to get your plow... er, shack off the ice and above the snow. Might be worth a look.
My guys and I are pulling the same shanty and the QuickFlip 2's, when the ice is to thin for our atv's or utv's early and late in the year. Here's what we do to make life a lot easier. The ole saying work smarter, not harder truly does apply. Especially since none of my crew and I are as young or in as good of shape as we once were.
Get yourself a deer drag set-up and attach it to the pulling rope on the sled and put the strap across your chest and mush. It's relatively easy to manually pull the shanty with your whole body, instead of just with the arms. If you don't already have a drag, you can pick one up, for not a lot of money and make your life and ice fishing experience easier to enjoy.
Take care and tight lines.
