Eliot just took his gear "as is" - no winterization. I've had numerous arctic explorers and extreme Himalayan climbers in my home, even living here. The simpler the equipment, the better (back then, that meant totally manual Nikon F-series cameras, classic old Pentax 35mm or 6x7 (battery, but no fancy electronics). I doubt that any tourist venue to the edge of Antarctica or to Paine NP is going to encounter conditions that extreme. Friends haven't had problems with typical cameras. But with a view camera you've always got the risk of lenses or a GG fogging up due to a sudden temp change. Gear can get blown over by wind gusts and instantly ruined. Seen it all. The less stuff, the better. But I would take a view camera if it were me. That's a rare opportunity.
