what you might consider is since you fish alone and have to set it up......you might build a sled that is raised up a bit (to reduce drag on the snow) and set the shanty on it. Its usually not the weight that kills you, its the drag or friction. I have seen a sled that used cross country ski's, I say 1 man tow what i would say to be 200 lbs of equipment thru 4 inches of snow with 1 hand. Yet my shany weighs 82 lbs empty, and I can barely drag it thru 4" snow with 2 hands. Its all about the sled.
