I use a couple differant sized otter sleds to pull ice fishing gear out onto the lake both on foot and behind an atv. They are about as tough as they come, I have yet to wear the bottom out even when I was using it to haul firewood out of the woods and over the gravel driveway. The one thing I didn't like about it was if the snow was soft and fluffy they tend to turn into a plow. They do have a nice lip that runs all the way around the top that you can attach a cover and straps to, and attach a rope rig so you can follow the sled down hill.
