It's basically a fully insulated version of the sentinel. They say it weighs 64 lbs. I have the recon which is actually a little smaller than that one and uninsulated, I love it for when I go out by myself and for early ice, when I'm trying to pack lite. As far as pulling, it all depends on how much gear you try to pack in it, I have skies on mine. I would probably second the smitty sled.
