I have the Medium Ice Cabin, 2 person, only I didn't get the bench seat or 2 swivel singles, I'm going to make something for this winter instead of folding beach chairs. The sled is made of thick poly, hardly any flex, the top material is pretty thick too, sewn in attachment goes all the way around and simply snaps on, no screwing needed, the superstructure is made of square poles, they expand and collapse without problems. I see the info sheet says 90lbs, maybe a mistake or I'm getting stronger(highly doubt it). Get the extra runners, they take up a lot of road wear, got mine at BPS for about $35, they should last 2-3 winters. I made my own tow bar, I have my MIG for that. So far, no complaints compared to that Pile of Bovine Excrement from Frabil the year before. It's long enough to accomodate the Jiffy auger. Unless you have someone with seamstress qualifications, maybe get the custom cover too, keeps your kit in and snowbanks out.
